Zero and Negative Exponents: Evaluating Expressions

The video tutorial covers evaluating expressions with zero and negative exponents. It explains that any non-zero number raised to the power of zero equals one, while a base of zero with an exponent of zero is undefined. Negative exponents represent reciprocals, and the video provides examples and practice problems to reinforce these concepts. The tutorial also explores algebraic expressions involving exponents, emphasizing the importance of converting negative exponents to positive by using reciprocals.

Provide an example of how to simplify an expression with a negative exponent.
