### About Exponent Rules:

In order to successfully perform operations with polynomials, one must have a complete understanding of the rules of exponents. We will review: the product rule for exponents, the quotient rule for exponents, the power rules for exponents, negative exponents, and the power of zero.

Test Objectives

- Demonstrate an understanding of the product/quotient rule for exponents
- Demonstrate an understanding of the power rules for exponents
- Demonstrate an understanding of negative exponents and the power of zero
