Exploring Negative Exponents in the Law of Exponents

The video tutorial covers the concept of negative exponents, explaining how they work and how to simplify expressions involving them. It introduces the rule that to make a negative exponent positive, you move the base to the opposite part of the fraction. The tutorial provides several examples to illustrate these concepts, including complex cases and shortcuts for dealing with fractions raised to negative powers. The session concludes with a summary of key points and additional practice problems.
