This module provides sample problems which develop concepts related to simplifying radicals.

Based on the generalization you wrote in #5 in the module "Some Very Important Generalizations", and given the fact that 4 × 2 = 8 , we can simplify 8 as follows:

8 = 4 × 2 (because 8 is the same thing as 4 × 2 )
4 × 2 = 4 × 2 (this is where we use that generalization)
4 × 2 = 2 2 (because 4 is the same thing as 2)

So, we see that 8 is the same thing as 2 2 .
