3. Squaring a square root Example: Why it makes sense: rewrite in exponential notation. In general, For example, HOWEVER, if n is even, Ex:

4. Ex. 1: Simplifying Cube Roots Simplify the expression. a) b) c) d)

5. How to Simplify n th Roots For : See how many times ____ goes into _____. This is the exponent that goes outside the radical. Find the remainder when ___ goes into ____. This is the exponent that goes inside the radical. Example:
