Unit 2 Day 7

Do now Simplify the square roots

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

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

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:

Ex. 2: Simplifying Radical Expressions Simplify the expression. Assume all variables are positive. a. b. c. d.

Ex. 3: Simplest Form Simplify the expression. Assume all variables are positive. a. b. c. d.
