Evaluating Square Roots

When the square root of a number is squared, the result is the original number. Since (4^2=16), the square root of (16) is (4).The square root function is the inverse of the squaring function just as subtraction is the inverse of addition. To undo squaring, we take the square root.

In general terms, if (a) is a positive real number, then the square root of (a) is a number that, when multiplied by itself, gives (a). The square root could be positive or negative because multiplying two negative numbers gives a positive number. However, the ( sqrt{ ext{ } } ) symbol denotes just the non-negative result, or so-called principal square root. The square root obtained using a calculator is the principal square root.

The principal square root is the nonnegative number that when multiplied by itself equals (a). The principal square root of (a) is written as (sqrt{a}). The symbol is called a radical, the term under the symbol is called the radicand, and the entire expression is called a radical expression.

Example (PageIndex{1})

Does (sqrt{25} = pm 5)?


No. Although both (5^2) and ((−5)^2) are (25), the radical symbol implies only a nonnegative root, the principal square root. The principal square root of (25) is (sqrt{25}=5).


The principal square root of (a) is the nonnegative number that, when multiplied by itself, equals (a). It is written as a radical expression (sqrt{a}), with the symbol called a radical, over the term (a), called the radicand. (sqrt{a}).

Example (PageIndex{2}): Evaluating Square Roots

Evaluate each expression.

  1. (sqrt{100})
  2. (sqrt{sqrt{16}})
  3. (sqrt{25+144})
  4. (sqrt{49})-(sqrt{81})


  1. (sqrt{100} =10) because (10^2=100)
  2. (sqrt{sqrt{16}}= sqrt{4} =2) because (4^2=16) and (2^2=4)
  3. (sqrt{25+144} = sqrt{169} =13) because (13^2=169)
  4. (sqrt{49} -sqrt{81} =7−9 =−2) because (7^2=49) and (9^2=81)

Example (PageIndex{3}):

For (sqrt{25+144}), can we find the square roots before adding?


No. (sqrt{25} + sqrt{144} =5+12=17). This is not equivalent to (sqrt{25+144}=13). The order of operations requires us to add the terms of the radicand together before finding the square root.

Using the Product Rule to Simplify Square Roots

To simplify a square root, we rewrite it such that there are no perfect squares in the radicand. There are several properties of square roots that allow us to simplify complicated radical expressions. The first rule we will look at is the product rule for simplifying square roots, which allows us to separate the square root of a product of two numbers into the product of two separate rational expressions. For instance, we can rewrite (sqrt{15}) as (sqrt{3} imessqrt{5}). We can also use the product rule to express the product of multiple radical expressions as a single radical expression.

The Product Rule For Simplifying Square Roots

If (a) and (b) are nonnegative, the square root of the product (ab) is equal to the product of the square roots of (a) and (b)

[sqrt{ab}=sqrt{a} imessqrt{b}]

HOWTO: Simplify the square root of a product.

  1. Factor any perfect squares from the radicand.
  2. Write the radical expression as a product of radical expressions.
  3. Simplify.

Example (PageIndex{4}): Using the Product Rule to Simplify Square Roots

Simplify the radical expression.

  1. (sqrt{300})
  2. (sqrt{162a^5b^4})


a. ( quad sqrt{100 imes3} ) Factor perfect square from radicand.

( sqrt{100} imessqrt{3} ) Write radical expression as product of radical expressions.

( 10sqrt{3}) Simplify

b. ( quad sqrt{81a^4b^4 imes2a}) Factor perfect square from radicand

(sqrt{81a^4b^4} imessqrt{2a}) Write radical expression as product of radical expressions

(9a^2b^2sqrt{2a}) Simplify

Simplify (sqrt{50x^2y^3z})



Notice the absolute value signs around (x) and (y)? That’s because their value must be positive!

Howto: Simplify the product of multiple radical expressions

  1. Express the product of multiple radical expressions as a single radical expression.
  2. Simplify.

Example (PageIndex{5}): Using the Product Rule to Simplify the Product of Multiple Square Roots

Multiply. Simplify the radical expression.

a. (sqrt{12} imessqrt{3})

b. (sqrt { 6 x ^ { 3 } y ^ { 3 } } imes sqrt{2 x^3} ).


a. ( quad ext{Express the product as a single radical expression: } sqrt{12 imes3} = sqrt{36} = 6 )

b. ( quad )Begin by writing as a single radical expression: (sqrt { 12 x ^ { 6 } y ^ { 3 } }).

Determine the square factors of (12, x^{ 6}) , and (y^{ 3}).

(left. egin{array} { l } { 12 = color{Cerulean}{2 ^ { 2} }color{black}{ cdot} 3 } { x ^ { 6 } = color{Cerulean}{left( x ^ { 3 } ight) ^ { 2 } }} { y ^ { 3 } = color{Cerulean}{y ^ { 2} }color{black}{ cdot} y } end{array} ight} quadcolor{Cerulean}{Square:factors})

Make these substitutions, and then apply the product rule for radicals and simplify.

(egin{aligned} sqrt { 12 x ^ { 6 } y ^ { 3 } } & = sqrt { color{Cerulean}{2 ^ { 2} }color{black}{ cdot} 3 cdot color{Cerulean}{left( x ^ { 3 } ight) ^ { 2 }}color{black}{ cdot}color{Cerulean}{ y ^ { 2} }color{black}{ cdot} y } quadquadquadquad:color{Cerulean} { Apply:the: product :rule: for: radicals. } & = sqrt { 2 ^ { 2 } } cdot sqrt { left( x ^ { 3 } ight) ^ { 2 } } cdot sqrt { y ^ { 2 } } cdot sqrt { 3 y } quadcolor{Cerulean} { Simplify. } & = 2 cdot x ^ { 3 } cdot | y | cdot sqrt { 3 y } & = 2 x ^ { 3 } | y | sqrt { 3 y } end{aligned})

Notice the absolute value bars around ( y ). That is because the result of taking a square root is never negative.

Using the Quotient Rule to Simplify Square Roots

Just as we can rewrite the square root of a product as a product of square roots, so too can we rewrite the square root of a quotient as a quotient of square roots, using the quotient rule for simplifying square roots.


The square root of the quotient (dfrac{a}{b}) is equal to the quotient of the square roots of (a) and (b) , where (a ge 0) and (b > 0) .


Howto: Simplify the radical of a quotient

  1. Simplify the quotient radicand.
  2. Write the simplified quotient radical expression as the quotient of two radical expressions.
  3. Simplify the numerator and denominator.

Example (PageIndex{6}): Using the Quotient Rule to Simplify Square Roots

Simplify the radical expression.

a. (sqrt{dfrac{5}{36}})b. (sqrt { dfrac { 18 a ^ { 5 } } { b ^ { 8 } } })


a. Write as a quotient of two radical expressions and then simplify the denominator: (dfrac{sqrt{5}}{sqrt{36} = dfrac{sqrt{5}}{6})

b. Begin by determining the square factors of (18), (a^{5}), and (b^{8}).

(left. egin{array} { l } { 18 = 2 cdot color{Cerulean}{3 ^ { 2} } } { a ^ { 5 } = a ^ { 2 } cdot a ^ { 2 } cdot a = color{Cerulean}{left( a ^ { 2 } ight) ^ { 2 }}color{black}{ cdot} a } { b ^ { 8 } = b ^ { 4 } cdot b ^ { 4 } quad::= color{Cerulean}{left( b ^ { 4 } ight) ^ { 2 }} } end{array}quad ight}quadcolor{Cerulean}{Square:factors})

( quad ) Make these substitutions, apply the product and quotient rules for radicals, and then simplify.

(egin{aligned} sqrt { frac { 18 a ^ { 5 } } { b ^ { 8 } } } & = sqrt { frac { 2 cdot color{Cerulean}{3 ^ { 2} }color{black}{ cdot}color{Cerulean}{ left( a ^ { 2 } ight) ^ { 2 }}color{black}{ cdot} a } { color{Cerulean}{left( b ^ { 4 } ight) ^ { 2 } } }}quadquadcolor{Cerulean}{Apply:the:product:and:quotient:rule:for:radicals.} & = frac { sqrt { 3 ^ { 2 } } cdot sqrt { left( a ^ { 2 } ight) ^ { 2 } } cdot sqrt { 2 a } } { sqrt { left( b ^ { 4 } ight) ^ { 2 } } }quad color{Cerulean}{Simplify.} & = frac { 3 a ^ { 2 } sqrt { 2 a } } { b ^ { 4 } } end{aligned})

Try It (PageIndex{6})

Simplify (sqrt{dfrac{2x^2}{9y^4}})


(dfrac{|x|sqrt{2}}{3y^2} quad ) We do not need the absolute value signs for (y^2) because that term will always be nonnegative.

Howto: Simplify the quotient of multiple radical expressions

  1. Express the quotient of multiple radical expressions as a quotient of a single radical expression.
  2. Simplify the radical.

Example (PageIndex{7}): Use the Quotient Rule to Simplify the Quotient of Two Square Roots

Divide. Simplify the radical expression.

a. (dfrac{sqrt{234x^{11}y}}{sqrt{26x^7y}})b. ( dfrac { sqrt {50 x^6 y^4} } { sqrt {8 x^3 y} } )


a. First combine numerator and denominator into one radical expression

dfrac { sqrt { 50 x ^ { 6 } y ^ { 4} } } { sqrt { 8 x ^ { 3 } y } }&=sqrt{dfrac{234x^{11}y}{26x^7y}} & & ext{Write under one radical}[5pt]
&=sqrt{9x^4} & & ext{Simplify radicand}[5pt]
&=3x^2 & & ext{Simplify square root}

b. Write as a single square root and cancel common factors before simplifying.

(egin{aligned} frac { sqrt { 50 x ^ { 6 } y ^ { 4 } } } { sqrt { 8 x ^ { 3 } y } } & = sqrt { frac { 50 x ^ { 6 } y ^ { 4 } } { 8 x ^ { 3 } y } } quadcolor{Cerulean}{Apply:the:quotient:rule:for:radicals:and:cancel.} & = sqrt { frac { 25 x ^ { 3 } y ^ { 3 } } { 4 } } quadcolor{Cerulean}{Simplify.} & = frac { sqrt { 25 x ^ { 3 } y ^ { 3 } } } { sqrt { 4 } } & = frac { 5 |x y| sqrt { x y } } { 2 } end{aligned})

Try It (PageIndex{7})

Simplify (dfrac{sqrt{9a^5b^{14}}}{sqrt{3a^4b^5}})



From this point on the assumption will be made that all variables represent non-negative real numbers. Therefore using absolute values when simplifying will not be necessary.

Adding and Subtracting Square Roots

We can add or subtract radical expressions only when they have the same radicand and when they have the same radical type such as square roots. For example, the sum of (sqrt{2}) and (3sqrt{2}) is (4sqrt{2}). However, it is often possible to simplify radical expressions, and that may change the radicand. The radical expression (sqrt{18}) can be written with a (2) in the radicand, as (3sqrt{2}), so (sqrt{2}+sqrt{18}=sqrt{2}+3sqrt{2}=4sqrt{2})

Howto: Simplify a radical expression requiring addition or subtraction of square roots

  1. Simplify each radical expression.
  2. Add or subtract expressions with equal radicands.

Often, we will have to simplify before we can identify the like radicals within the terms. If the radicand and the index are not exactly the same, then the radicals are not similar and we cannot combine them.

Example​ (PageIndex{8}): Add or Subtract Square Roots

Perform the indicated operation and simplify.

  1. (4 sqrt { 10 } - 5 sqrt { 10 } )
  2. (5sqrt{12}+2sqrt{3}).
  3. (20sqrt{72a^3b^4c}-14sqrt{8a^3b^4c})


a. (egin{aligned} ext{ }& ext{ } & ext{ } && = ( 4 - 5 ) sqrt { 10 } & & &= - 1 sqrt { 10 } & & &= - sqrt { 10 } end{aligned})

b. ( quad )We can rewrite (5sqrt{12}) as (5sqrt{4 imes3}). According the product rule, this becomes (5sqrt{4}sqrt{3}). The square root of (sqrt{4}) is (2) , so the expression becomes (5 imes2sqrt{3}), which is (10sqrt{3}). Now we can the terms have the same radicand so we can add.

[10sqrt{3}+2sqrt{3}=12sqrt{3} onumber]

c. ( quad )Rewrite each term so they have equal radicands.

[egin{align*} 20sqrt{72a^3b^4c} &= 20sqrt{9}sqrt{4}sqrt{2}sqrt{a}sqrt{a^2}sqrt{(b^2)^2}sqrt{c} &= 20(3)(2)|a|b^2sqrt{2ac} &= 120|a|b^2sqrt{2ac} end{align*}]

[egin{align*} 14sqrt{8a^3b^4c} &= 14sqrt{2}sqrt{4}sqrt{a}sqrt{a^2}sqrt{(b^2)^2}sqrt{c} &= 14(2)|a|b^2sqrt{2ac} &= 28|a|b^2sqrt{2ac} end{align*}]

Now the terms have the same radicand so we can subtract.


Try It (PageIndex{8})

  1. Add (sqrt{5}+6sqrt{20})
  2. Subtract (3sqrt{80x}-4sqrt{45x})

a. (13sqrt{5}) ( qquad ) b. (0)

Example (PageIndex{9}): Adding and Subtracting Square Roots


  1. ( 10 sqrt { 5 } + 6 sqrt { 2 } - 9 sqrt { 5 } - 7 sqrt { 2 } )
  2. ( sqrt { 32 } - sqrt { 18 } + sqrt { 50 } )
  3. (2 a sqrt { 125 a ^ { 2 } b } - a ^ { 2 } sqrt { 80 b } + 4 sqrt { 20 a ^ { 4 } b }).



(egin{aligned} & ext{ } && = color{Cerulean}{10 sqrt { 5 } - 9 sqrt { 5 }}color{black}{ +}color{OliveGreen}{ 6 sqrt { 2 } - 7 sqrt { 2 }} &&& = sqrt { 5 } - sqrt { 2 } end{aligned})

We cannot simplify any further because (sqrt{5}) and (sqrt{2}) are not like radicals; the radicands are not the same.
(color{YellowOrange}{ ext{Caution:}}) It is important to point out that (sqrt { 5 } - sqrt { 2 } eq sqrt { 5 - 2 }). We can verify this by calculating the value of each side with a calculator.

( sqrt { 5 } - sqrt { 2 } approx 0.82 qquad ext{ is not the same as } qquad sqrt { 5 - 2 } = sqrt { 3 } approx 1.73 )


(egin{aligned} & ext{ } && = sqrt { 16 } cdot 2 - sqrt { 9 cdot 2 } + sqrt { 25 cdot 2 } &&& = 4 sqrt { 2 } - 3 sqrt { 2 } + 5 sqrt { 2 } &&& = 6 sqrt { 2 } end{aligned})

At first glance, the radicals do not appear to be similar. However, after simplifying completely, we see that we can combine them.

c. ( ;) Step 1: Simplify the radical expression.
( quad ) Step 2: Combine all like radicals. Remember to add only the coefficients; the variable parts remain the same.

(egin{array} { l } { 2 a sqrt { 125 a ^ { 2 } b } - a ^ { 2 } sqrt { 80 b } + 4 sqrt { 20 a ^ { 4 } b } } { = 2 a sqrt { 25 cdot 5 cdot a ^ { 2 } cdot b } - a ^ { 2 } sqrt { 16 cdot 5 cdot b } + 4 sqrt { 4 cdot 5 cdot left( a ^ { 2 } ight) ^ { 2 } b } }quadcolor{Cerulean}{Factor.} { = 2 a cdot 5 cdot a sqrt { 5 b } - a ^ { 2 } cdot 4 sqrt { 5 b } + 4 cdot 2 cdot a ^ { 2 } sqrt { 5 b } } quadquadquadquadquad:color{Cerulean}{ Simplify.} { = 10 a ^ { 2 } sqrt { 5 b } - 4 a ^ { 2 } sqrt { 5 b } + 8 a ^ { 2 } sqrt { 5 b } } quadquadquadquadquadquadquadquadquad color{Cerulean}{Combine:like:terms.} { = 14 a ^ { 2 } sqrt { 5 b } } end{array})

Try It (PageIndex{9})

Simplify: (sqrt { 20 } + sqrt { 27 } - 3 sqrt { 5 } - 2 sqrt { 12 }).


(- sqrt { 5 } - sqrt { 3 })


Take careful note of the differences between products and sums within a radical. Assume both (x) and (y) are nonnegative.

(egin{array} { l } Products quad quadquadquad Sumshline { sqrt { x ^ { 2 } y ^ { 2 } } = x y quadsqrt { x ^ { 2 } + y ^ { 2 } } eq x + y } end{array})

The property says that we can simplify radicals when the operation in the radicand is multiplication. There is no corresponding property for addition.

Simplifying Products of Expressions containing Square Roots

Often, there will be coefficients in front of the radicals.

Example (PageIndex{10.1x}):

Multiply: (3 sqrt { 6 } cdot 5 sqrt { 2 })


Using the product rule for radicals and the fact that multiplication is commutative, we can multiply the coefficients and the radicands as follows.

(egin{aligned} 3 sqrt { 6 } cdot 5 sqrt { 2 } & = color{Cerulean}{3 cdot 5}color{black}{ cdot}color{OliveGreen}{ sqrt { 6 } cdot sqrt { 2} }quadcolor{Cerulean}{Multiplication:is:commutative.} & = 15 cdot sqrt { 12 } quadquadquad:color{Cerulean}{Multiply:the:coefficients:and:the:radicands.} & = 15 sqrt { 4 cdot 3 } quadquadquad:color{Cerulean}{Simplify.} & = 15 cdot 2 cdot sqrt { 3 } & = 30 sqrt { 3 } end{aligned})

Typically, the first step involving the application of the commutative property is not shown.

We will often find the need to subtract a radical expression with multiple terms. If this is the case, remember to apply the distributive property before combining like terms.

Example (PageIndex{10.2x}): Use the distributive property with square roots

(egin{aligned} & ext{Simplify: } ( 5 sqrt { x } - 4 sqrt { y } ) - ( 4 sqrt { x } - 7 sqrt { y } ) && ext{Solution:} ext{ }& ext{ } & ext{ } && = 5 sqrt { x } - 4 sqrt { y } - 4 sqrt { x } + 7 sqrt { y } quadcolor{Cerulean}{Distribute.} &&& = 5 sqrt { x } - 4 sqrt { x } - 4 sqrt { y } + 7 sqrt { y } &&& = sqrt { x } + 3 sqrt { y } end{aligned})

Use the distributive property when multiplying rational expressions with more than one term.

Example (PageIndex{10.3x}):

Multiply: (5 sqrt { 2 x } ( 3 sqrt { x } - sqrt { 2 x } )).


Apply the distributive property and multiply each term by (5 sqrt { 2 x }).

(egin{aligned} 5 sqrt { 2 x } ( 3 sqrt { x } - sqrt { 2 x } ) & = color{Cerulean}{5 sqrt { 2 x } }color{black}{cdot} 3 sqrt { x } - color{Cerulean}{5 sqrt { 2 x }}color{black}{ cdot} sqrt { 2 x } quadcolor{Cerulean}{Distribute.} & = 15 sqrt { 2 x ^ { 2 } } - 5 sqrt { 4 x ^ { 2 } } quadquadquadquad:::color{Cerulean}{Simplify.} & = 15 x sqrt { 2 } - 5 cdot 2 x & = 15 x sqrt { 2 } - 10 x end{aligned})

The process for multiplying radical expressions with multiple terms is the same process used when multiplying polynomials. Apply the distributive property, simplify each radical, and then combine like terms.

Example (PageIndex{10.4x}):

Multiply: (( sqrt { x } - 5 sqrt { y } ) ^ { 2 }).


(( sqrt { x } - 5 sqrt { y } ) ^ { 2 } = ( sqrt { x } - 5 sqrt { y } ) ( sqrt { x } - 5 sqrt { y } ))

Begin by applying the distributive property.

(egin{array} { l } { = color{Cerulean}{sqrt { x }}color{black}{ cdot} sqrt { x } + color{Cerulean}{sqrt { x }}color{black}{ (} - 5 sqrt { y } ) + ( color{OliveGreen}{- 5 sqrt { y }}color{black}{ )} sqrt { x } + ( color{OliveGreen}{- 5 sqrt { y }}color{black}{ )} ( - 5 sqrt { y } ) } { = sqrt { x ^ { 2 } } - 5 sqrt { x y } - 5 sqrt { x y } + 25 sqrt { y ^ { 2 } } } { = x - 10 sqrt { x y } + 25 y } end{array})

The binomials ((a + b)) and ((a − b)) are called conjugates. When multiplying conjugate binomials the middle terms are opposites and their sum is zero.

Example (PageIndex{10.5x}):

Multiply: (( sqrt { 10 } + sqrt { 3 } ) ( sqrt { 10 } - sqrt { 3 } )).


Apply the distributive property, and then combine like terms.

(egin{aligned} ( sqrt { 10 } + sqrt { 3 } ) ( sqrt { 10 } - sqrt { 3 } ) & = color{Cerulean}{sqrt { 10} }color{black}{ cdot} sqrt { 10 } + color{Cerulean}{sqrt { 10} }color{black}{ (} - sqrt { 3 } ) + color{OliveGreen}{sqrt{3}}color{black}{ (}sqrt{10}) + color{OliveGreen}{sqrt{3}}color{black}{(}-sqrt{3}) & = sqrt { 100 } - sqrt { 30 } + sqrt { 30 } - sqrt { 9 } & = 10 - color{red}{sqrt { 30 }}color{black}{ +}color{red}{ sqrt { 30} }color{black}{ -} 3 & = 10 - 3 & = 7 end{aligned})

It is important to note that when multiplying conjugate radical expressions, we obtain a rational expression. This is true in general

(egin{aligned} ( sqrt { x } + sqrt { y } ) ( sqrt { x } - sqrt { y } ) & = sqrt { x ^ { 2 } } - sqrt { x y } + sqrt {x y } - sqrt { y ^ { 2 } } & = x - y end{aligned})

Alternatively, using the formula for the difference of squares we have,

(egin{aligned} ( a + b ) ( a - b ) & = a ^ { 2 } - b ^ { 2 }quadquadquadcolor{Cerulean}{Difference:of:squares.} ( sqrt { x } + sqrt { y } ) ( sqrt { x } - sqrt { y } ) & = ( sqrt { x } ) ^ { 2 } - ( sqrt { y } ) ^ { 2 } & = x - y end{aligned})

Try It (PageIndex{10x})

Multiply: (( 3 - 2 sqrt { y } ) ( 3 + 2 sqrt { y } )). (Assume (y) is positive).



Rationalizing Denominators

When an expression involving square root radicals is written in simplest form, it will not contain a radical in the denominator. We can remove radicals from the denominators of fractions using a process called rationalizing the denominator.

We know that multiplying by (1) does not change the value of an expression. We use this property of multiplication to change expressions that contain radicals in the denominator. To remove radicals from the denominators of fractions, multiply by the form of (1) that will eliminate the radical.

Monomial Denominators

For a denominator containing a single term, multiply by the radical in the denominator over itself. In other words, if the denominator is (bsqrt{c}), multiply by (dfrac{sqrt{c}}{sqrt{c}}).

HowTo: Given an expression with a single square root radical term in the denominator, rationalize the denominator

  1. Multiply the numerator and denominator by the radical in the denominator.
  2. Simplify.

Sometimes, we will find the need to reduce, or cancel, after rationalizing the denominator.

Example (PageIndex{11}): Rationalize a Denominator Containing a Single Term

Write in simplest form (rationalize the denominator).

a. ( dfrac{2sqrt{3}}{3sqrt{10}} )b. (dfrac { sqrt { 2 } } { sqrt { 5 x } })c. (dfrac { 3 a sqrt { 2 } } { sqrt { 6 a b } })


a. The radical in the denominator is (sqrt{10}). So multiply the fraction by (dfrac{sqrt{10}}{sqrt{10}}). Then simplify.

( dfrac{2sqrt{3}}{3sqrt{10}} imes {color{Cerulean}{ dfrac{sqrt{10}}{sqrt{10}} } } = dfrac{2sqrt{30}}{30} = dfrac{sqrt{30}}{15} )

b. The goal is to find an equivalent expression without a radical in the denominator. The radicand in the denominator determines the factors that you need to use to rationalize it. In this example, multiply by (1) in the form (frac { sqrt { 5 x } } { sqrt { 5 x } }).

(egin{aligned} frac { sqrt { 2 } } { sqrt { 5 x } } & = frac { sqrt { 2 } } { sqrt { 5 x } } cdot color{Cerulean}{frac { sqrt { 5 x } } { sqrt { 5 x } } } & = frac { sqrt { 10 x } } { sqrt { 25 x ^ { 2 } } } quadquad: color{Cerulean} { Simplify. } & = frac { sqrt { 10 x } } { 5 x } end{aligned})

c. In this example, we will multiply by (1) in the form (frac { sqrt { 6 a b } } { sqrt { 6 a b } }).

(egin{aligned} frac { 3 a sqrt { 2 } } { sqrt { 6 a b } } & = frac { 3 a sqrt { 2 } } { sqrt { 6 a b } } cdot color{Cerulean}{frac { sqrt { 6 a b } } { sqrt { 6 a b } }} & = frac { 3 a sqrt { 12 a b } } { sqrt { 36 a ^ { 2 } b ^ { 2 } } } quadquadcolor{Cerulean}{Simplify.} & = frac { 3 a sqrt { 4 cdot 3 a b} } { 6 ab } & = frac { 6 a sqrt { 3 a b } } { b }quadquad::color{Cerulean}{Cancel.} & = frac { sqrt { 3 a b } } { b } end{aligned})

Notice that (b) does not cancel in this example. Do not cancel factors inside a radical with those that are outside.

Write in simplest form (rationalize the denominator).

a. (dfrac{12sqrt{3}}{sqrt{2}})b. (sqrt { dfrac { 9 x } { 2 y } })

a. (6sqrt{6}) ( qquad ) b. (frac { 3 sqrt { 2xy } } { 2 y })

Binomial Denominators

For a denominator containing the sum or difference of rational or irrational terms, multiply the numerator and denominator by the conjugate of the denominator, which is found by changing the sign that connects the two terms in the denominator. If the denominator is (a+bsqrt{c}) , then the conjugate is (a-bsqrt{c}).

How to: Given an expression with a radical term and a constant in the denominator, rationalize the denominator

  1. Find the conjugate of the denominator.
  2. Multiply the numerator and denominator by the conjugate.
  3. Use the distributive property.
  4. Simplify.

Example (PageIndex{12}): Rationalizing a Denominator Containing Two Terms

Write in simplest form (rationalize the denominator).

a. (dfrac{4}{1+sqrt{5}})b. (dfrac { 1 } { sqrt { 5 } - sqrt { 3 } })c. (dfrac { sqrt { 10 } } { sqrt { 2 } + sqrt { 6 } })d. (dfrac { sqrt { x } - sqrt { y } } { sqrt { x } + sqrt { y } })


a. Begin by finding the conjugate of the denominator by writing the denominator and changing the sign. So the conjugate of (1+sqrt{5}) is (1-sqrt{5}). Then multiply the fraction by ( frac{1-sqrt{5}}{1-sqrt{5}}) .

b. In this example, the conjugate of the denominator is (sqrt { 5 } + sqrt { 3 }). Therefore, multiply by (1) in the form (frac { ( sqrt { 5 } + sqrt { 3 } ) } { ( sqrt {5 } + sqrt { 3 } ) }).

(egin{aligned} frac { 1 } { sqrt { 5 } - sqrt { 3 } } & = frac { 1 } { ( sqrt { 5 } - sqrt { 3 } ) } color{Cerulean}{frac { ( sqrt { 5 } + sqrt { 3 } ) } { ( sqrt { 5 } + sqrt { 3 } ) } ::Multiply :by:"1".} & = frac { sqrt { 5 } + sqrt { 3 } } { sqrt { 25 } + sqrt { 15 } - sqrt{15}-sqrt{9} } :color{Cerulean}{Simplify.} & = frac { sqrt { 5 } + sqrt { 3 } } { 5-3 } & = frac { sqrt { 5 } + sqrt { 3 } } { 2 } end{aligned})

Notice that the terms involving the square root in the denominator are eliminated by multiplying by the conjugate. We can use the property (( sqrt { a } + sqrt { b } ) ( sqrt { a } - sqrt { b } ) = a - b) to expedite the process of multiplying the expressions in the denominator.

c. Multiply by (1) in the form (frac { sqrt { 2 } - sqrt { 6 } } { sqrt { 2 } - sqrt { 6 } }).

(egin{aligned} frac{sqrt{10}}{sqrt{2}+sqrt{6} }&= frac{(sqrt{10})}{(sqrt{2}+sqrt{6})} color{Cerulean}{frac{(sqrt{2}-sqrt{6})}{(sqrt{2}-sqrt{6})}quadquad Multiple:by:the:conjugate.} &= frac { sqrt { 20 } - sqrt { 60 } } { 2 - 6 } quadquadquadquadquadquad:::color{Cerulean}{Simplify.} &= frac { sqrt { 4 cdot 5 } - sqrt { 4 cdot 15 } } { - 4 } &= frac { 2 sqrt { 5 } - 2 sqrt { 15 } } { - 4 } &=frac{2(sqrt{5}-sqrt{15})}{-4} &= frac { sqrt { 5 } - sqrt { 15 } } { - 2 } = - frac { sqrt { 5 } - sqrt { 15 } } { 2 } = frac { - sqrt { 5 } + sqrt { 15 } } { 2 } end{aligned})

d. In this example, we will multiply by (1) in the form (frac { sqrt { x } - sqrt { y } } { sqrt { x } - sqrt { y } }).

9.3 Add and Subtract Square Roots

We know that we must follow the order of operations to simplify expressions with square roots. The radical is a grouping symbol, so we work inside the radical first. We simplify 2 + 7 2 + 7 in this way:

2 + 7 Add inside the radical. 9 Simplify. 3 2 + 7 Add inside the radical. 9 Simplify. 3

Trying to add square roots with different radicands is like trying to add unlike terms.

But, just like we can add x + x , we can add 3 + 3 . x + x = 2 x 3 + 3 = 2 3 But, just like we can add x + x , we can add 3 + 3 . x + x = 2 x 3 + 3 = 2 3

Adding square roots with the same radicand is just like adding like terms. We call square roots with the same radicand like square roots to remind us they work the same as like terms.

Like Square Roots

Square roots with the same radicand are called like square roots .

We add and subtract like square roots in the same way we add and subtract like terms. We know that 3 x + 8 x 3 x + 8 x is 11 x 11 x . Similarly we add 3 x + 8 x 3 x + 8 x and the result is 11 x . 11 x .

Add and Subtract Like Square Roots

Think about adding like terms with variables as you do the next few examples. When you have like radicands, you just add or subtract the coefficients. When the radicands are not like, you cannot combine the terms.

Simplify: 4 3 y − 7 3 y + 2 3 y 4 3 y − 7 3 y + 2 3 y .

When radicals contain more than one variable, as long as all the variables and their exponents are identical, the radicals are like.

Example 9.35

Simplify: 3 x y + 5 3 x y − 4 3 x y 3 x y + 5 3 x y − 4 3 x y .

Simplify: 3 7 m n + 7 m n − 4 7 m n 3 7 m n + 7 m n − 4 7 m n .

Add and Subtract Square Roots that Need Simplification

Remember that we always simplify square roots by removing the largest perfect-square factor. Sometimes when we have to add or subtract square roots that do not appear to have like radicals , we find like radicals after simplifying the square roots.

    Subsection 6.5.1 Square and (n)th Root Properties

    In Section 6.1 we defined the square root (sqrt) and (n)th root (sqrt[n]) radicals. When (x) is positive, the expression (sqrt[n]) means a positive number (r ext<,>) where (overbrace^>=x ext<.>) The square root (sqrt) is just the case where (n=2 ext<.>)

    When (x) is negative, (sqrt[n]) might not be defined. It depends on whether or not (n) is an even number. When (x) is negative and (n) is odd, (sqrt[n]) is a negative number where (overbrace^>=x ext<.>)

    There are two helpful rules for simplifying radicals.

    List 6.5.1. Rules of Radicals for Multiplication and Division

    If (a) and (b) are positive real numbers, and (m) is a positive integer , then we have the following rules:

    Checkpoint 6.5.2 .

    Subsection 6.5.2 Rationalizing the Denominator

    In Section 6.2 we covered how to rationalize the denominator when it contains a single square root or a binomial with a square root term.

    Example 6.5.3 .

    Rationalize the denominator of the expressions.

    First we will simplify (sqrt<75> ext<.>)

    Now we can rationalize the denominator by multiplying the numerator and denominator by (sqrt<3> ext<.>)

    Example 6.5.4 . Rationalize Denominator Using the Difference of Squares Formula.

    Rationalize the denominator in (frac-sqrt<5>>+sqrt<2>> ext<.>)

    To remove radicals in (sqrt<3>+sqrt<2>) with the difference of squares formula, we multiply it with (sqrt<3>-sqrt<2> ext<.>)

    3 Answers 3

    This was going to be a comment, but it got kind of long so I'm putting it here:

    A big "gotcha' worth acknowledging is $sqrt$ has no "positive" option once we allow complex inputs. The ability to take the positive root is an artifact of the real numbers. We obviously want $sqrt$ to be continuous, so you might try to just extend the positive branch of $sqrt$ to the complex numbers.

    The unfortunate fact is there is no way to do this. The $sqrt$ function is (in a way that complex analysis makes precise) inherently discontinuous. However, we can repair the situation in a number of ways:

    Restricting the domain of $sqrt$ . This is basically the same as saying "don't take square roots of negative numbers". There are lots of possible "branch cuts" that you can take, but no matter what you do you'll be left with a discontinuity, which we typically treat as an undefined region.

    Changing the domain to a riemann surface. This is really the "best" solution for a number of reasons, though it is conceptually difficult.

    Allowing multi-valued functions. The issue with making $sqrt$ continuous in $mathbb C$ is this: Start at $z$ , and remember $sqrt$ . Then make a lap around the origin, taking note of $sqrt$ as you go (this should be continuously, of course). When you get back to $z$ , you'll find $-sqrt$ instead of what you started with! So we can "solve this problem" by just asserting $pm sqrt$ is the output. Then when we make a lap around the origin, we start at $pm sqrt$ and we end at $mp sqrt$ , which is the same! Our problem has "gone away", but at the cost of changing what it means to be a function.

    This problem really doesn't come to light until you start playing with Complex Analysis, but $sqrt$ and $log(cdot)$ are the two most famous examples of this phenomenon. Congratulations on running into it! This exact "issue" with complex numbers is responsible for tons of recent mathematics, with really beautiful geometry to show for it.

    While the intimidating sight of a square root symbol may make the mathematically-challenged cringe, square root problems are not as hard to solve as they may first seem. Simple square root problems can often be solved as easily as basic multiplication and division problems. More complex square root problems, on the other hand, can require some work, but with the right approach, even these can be easy.

    How to Add Square Roots

    The radicand refers to the number under the radical sign. In the radical below, the radicand is the number '5'.

    How to Add Simplified Square Roots?

    Let's look at the following example

    You can only add square roots (or radicals) that have the same radicand. So in the example above you can add the first and the last terms:

    The same rule goes for subtracting. Consider the following example:

    You can subtract square roots with the same radicand--which is the first and last terms.

    Practice Problems

    Directions:Add the square roots below

    Problem 1

    Only the first and last square root have the same radicand, so you can add these two terms.

    Problem 2

    Remember--the same rule applies to subtracting square roots--the radicands must be the same.

    How to Add Square Roots- that are not simplified

    Let's look at the following example

    You may immediately see the problem here: The radicands are not the same. Therefore, we can not add them at the moment. However, if we simplify the square roots first, we will be able to add them. Let's use this example problem to illustrate the general steps for adding square roots.

    Subsection 14.5.1 Introduction to Radical Functions

    In Section 14.1 we covered the square root and other root functions. We learned how to find the domain of radical functions algebraically and the range graphically. We also saw the distance formula which is an application of square roots.

    Example 14.5.1 The Square Root Function

    Algebraically find the domain of the function (f) where (f(x)=sqrt<3x-1>+2) and then find the range by making a graph.

    Using Fact 14.1.29 to find the function's domain, we set the radicand greater than or equal to zero and solve:

    The function's domain is (left[frac<1><3>,infty ight)) in interval notation.

    To find the function's range, we use technology to look at a graph of the function. The graph shows that the function's range is ([2,infty) ext<.>) The graph also verifies the function's domain is indeed (left[frac<1><3>,infty ight) ext<.>)

    Example 14.5.3 The Distance Formula

    Find the distance between ((6,-13)) and ((-4,17) ext<.>)

    To calculate the distance between ((6,-13)) and ((-4,17) ext<,>) we use the distance formula. It's good practice to mark each value with the corresponding variables in the formula:

    The distance between ((6,-13)) and ((-4,17)) is (10sqrt<10>) or approximately (31.62) units.

    Example 14.5.4 The Cube Root Function

    Algebraically find the domain and graphically find the range of the function (g) where (g(x)=-2sqrt[3]-1 ext<.>)

    First note that the index of the function (g) for (g(x)=-2sqrt[3]-1) is odd. By Fact 14.1.29, the domain is ((-infty,infty) ext<.>)

    To find the function's range, we use technology to graph the function. According to the graph, the function's range is also ((-infty,infty) ext<.>)

    Example 14.5.6 Other Roots

    Algebraically find the domain and graphically find the range of the function (h) where (h(x)=8-frac<5><2>sqrt[4]<6-2x> ext<.>)

    First note that the index of this function is (4 ext<,>) which is even. By Fact 14.1.29, to find the domain of this function we must set the radicand greater or equal to zero and solve.

    So, the domain of (h) is ((-infty,3] ext<.>)

    To find the function's range, we use technology to graph the function. By the graph, the function's range is ((-infty,8] ext<.>)

    Subsection 14.5.2 Radical Expressions and Rational Exponents

    Example 14.5.8 Radical Expressions and Rational Exponents

    Simplify the expressions using Fact 14.2.2 or Fact 14.2.10.

    In this problem the negative can be associated with either the numerator or the denominator, but not both. We choose the numerator.

    Example 14.5.9 More Expressions with Rational Exponents

    Use exponent properties in List 14.2.15 to simplify the expressions, and write all final versions using radicals.

    Subsection 14.5.3 More on Rationalizing the Denominator

    In Section 14.3 we covered how to rationalize the denominator when it contains a single square root or a binomial.

    Example 14.5.10 A Review of Rationalizing the Denominator

    Rationalize the denominator of the expressions.

    First we will simplify (sqrt<75> ext<.>)

    Now we can rationalize the denominator by multiplying the numerator and denominator by (sqrt<3> ext<.>)

    Example 14.5.11 Rationalize Denominator with Difference of Squares Formula

    Rationalize the denominator in (frac-sqrt<5>>+sqrt<2>> ext<.>)

    To remove radicals in (sqrt<3>+sqrt<2>) with the difference of squares formula, we multiply it with (sqrt<3>-sqrt<2> ext<.>)

    Subsection 14.5.4 Solving Radical Equations

    In Section 14.4 we covered solving equations that contain a radical. We learned about extraneous solutions and the need to check our solutions.

    Example 14.5.12 Solving Radical Equations

    Solve for (r) in (r=9+sqrt ext<.>)

    We will isolate the radical first, and then square both sides.

    Because we squared both sides of an equation, we must check both solutions.

    It turns out (6) is an extraneous solution and (13) is a valid solution. So the equation has one solution: (13 ext<.>) The solution set is (<13> ext<.>)

    Example 14.5.13 Solving Radical Equations that Require Squaring Twice

    Solve the equation (sqrt=-1-sqrt) for (t ext<.>)

    We cannot isolate two radicals, so we will simply square both sides, and later try to isolate the remaining radical.

    Because we squared both sides of an equation, we must check the solution by substituting (substitute<16>) into (sqrt=-1-sqrt ext<,>) and we have:

    Our solution did not check so there is no solution to this equation. The solution set is the empty set, which can be denotes (< ext< >>) or (emptyset ext<.>)

    Properties of Roots

    Every positive real number has a positive nth root and the rules for operations with such roots obey the following rules:

    We can convert any expression with radicals into an exponent form:

    Using the exponent form makes it easier to cancel out powers and roots. We will cover exponent rules in more depth in the next chapter.

    Since roots are special cases of exponents, radical rules are essentially exponent rules written with a different notation, the radical symbol.
