There are 2 parts to a square root.
- the RADICAL
- the RADICAND
The radical tells us that we’re looking for identical factors.
The radicand is a number that needs to be factored so we can pull out the identical ones.
Example: since there are 2 5’s
Procedure
Simplify
Step 1: factor the radicand
Step 2: pull out factors that a repeated twice.
Step 3: Doubled factors are removed from the radical and made single. All other factors stay inside the radical.
Step 4: Simplify
