Simplify Radical Expressions Section 11.2

The Concept The last time we were together we talked about simplify radicals Today we’re going to review some concepts and then do some practice problems

The shift Radicals are easy for us if we accept one simple shift This shift allows us to use our rules of exponents as opposed to using a second set of rules for radicals

Example Simplify the radical Let’s split that into our perfect squares Convert back into “proper” radical form
