Section 4.2
Multiplying and Dividing Radical Expressions Pages 238-245
Review: Simplify each radical (not in book)
Note: Simplify means take everything out of the radical that you can.
Simplifying more radicals…
Note: If the radicand (what’s under the radical) doesn’t come out evenly, you will be left with a radical in your answer.
*Only combine directly if the index is the same.
