Simplifying Negative Exponents and Powers of Zero

This video tutorial introduces the concepts of zero and negative exponents, explaining their rules and applications. It covers the mathematical reasoning behind these rules and provides examples to illustrate how they work. The tutorial also includes proofs to demonstrate why these rules hold true and offers practice problems to help solidify understanding.
