09 - Simplify Radicals (Square Roots) w/ Multiplication and Division, Part 1

View more at http://www.MathTutorDVD.com. In this lesson, you will learn how to simplify radical expressions that are multiplied together or divided. We will use the rules for radical multiplication and division that we have learned in a previous lesson. The core concept is that when when two radicals (square roots or cube roots) are multiplied together, you can bring them under on single radical multiplied together. Similarly, if one radical is divided by another radical, you can perform the division under one single radical.
