1
Simplifying Radicals

2
Perfect Squares

3
= 2 = 4 = 5 = 10 = 12

4
= = = = = = = = = = Perfect Square Factor * Other Factor LEAVE IN RADICAL FORM

5
= = = = = = = = = = Perfect Square Factor * Other Factor LEAVE IN RADICAL FORM

6
+ To combine radicals: combine the coefficients of like radicals

7
Simplify each expression

8
Simplify each expression: Simplify each radical first and then combine.

= = = = = = = = = = Perfect Square Factor * Other Factor LEAVE IN RADICAL FORM

11
Simplify each expression

12

13
* To multiply radicals: multiply the coefficients and then multiply the radicands and then simplify the remaining radicals.

14
Multiply and then simplify

15

16
To divide radicals: divide the coefficients, divide the radicands if possible, and rationalize the denominator so that no radical remains in the denominator

17

18
This cannot be divided which leaves the radical in the denominator. We do not leave radicals in the denominator. So we need to rationalize by multiplying the fraction by something so we can eliminate the radical in the denominator. 42 cannot be simplified, so we are finished.

This can be divided which leaves the radical in the denominator. We do not leave radicals in the denominator. So we need to rationalize by multiplying the fraction by something so we can eliminate the radical in the denominator.

20
This cannot be divided which leaves the radical in the denominator. We do not leave radicals in the denominator. So we need to rationalize by multiplying the fraction by something so we can eliminate the radical in the denominator. Reduce the fraction.
