Understanding Negative Powers and Exponents

This video tutorial covers three important properties of exponents that students often forget. It explains how to handle fractions raised to negative powers by reciprocating them, converting radicals into rational powers, and applying the power to product and quotient rules. The tutorial emphasizes the importance of distributing powers across terms in expressions and clarifies common misconceptions.
