Lesson Summary:

In this lesson, we dive into the Quotient Rule for exponents and the meaning of zero exponents. The Quotient Rule states that if you have the same base in the numerator and the denominator, you write the base once and subtract the exponents. We also learn that any number, except zero, to the power of zero equals one, and that x to the negative power will be explained in the next video. Be careful not to assume that the answer to a quotient problem is one, as it depends on the exponents of the base.

The concept of dividing variable expressions with the same base is explained in this lesson. The quotient rule in the law of exponents is explained with many different example problems to show how it works. Some of the examples get pretty complicated. All of these examples eventually lead to finding out what a zero exponent means. Then, many examples of simplifying variable expressions with zero exponents are explained. This video series is great to check out if you are learning how to simplify exponent expressions.
