Lesson Summary:

In this lesson on Square Roots and Radicals, the Quotient Rule is used to divide square roots and rationalize denominators with square roots in them. The instructor demonstrates various methods and shortcuts to simplify square roots, including factoring and multiplying by perfect squares. Students are encouraged to choose the method that makes the most sense to them when solving problems. The lesson concludes by previewing higher-level problems to come in the next video.

Lesson Description:

Square Roots and Radicals Part 16 covers dividing with square roots using the quotient rule. Explains rationalizing the denominator for monomials with square roots in the denominator. Continuation of Part 16 with more examples.

This lesson shows many more examples and techniques for a math procedure introduced in the previous lesson called rationalizing the denominator. A couple of shortcut methods are shown in this lesson for getting the square root out of the denominator. All steps for these methods are explained completely. This is a very important lesson for future Algebraic problems.
