 WE SAY THAT A RADICAL is "simplified" when the radical has no square factors.square  What is a square factor?  A square factor is one of the square numbers that we listed on the last slide (the numbers in red) Square numbers Square roots

The square root of a product is equal to the product of the square roots of each factor.

 Simplify :  Step 1: List the factors  Step 2: Are there any square factors?  Step 3: Pull square factors out by taking the square root

 Simplify  List the factors

 Simplify

 Simplify H ERE IS THE RULE for multiplying radicals:

 You have to remove the radical when it is in the denominator place
