This document discusses properties of exponents when multiplying terms with the same base. It states that when multiplying terms with the same base, such as am * an, the exponents add, so the result is am+n. It provides examples of simplifying expressions using this rule, such as 8^4 * 8^2 = 8^6. The document also discusses operations involving scientific notation and negative exponents, providing practice problems for students to work through.
