Exponent Rules and Negative Exponents Explained

The video tutorial explains how to simplify expressions with negative exponents through examples. It starts with a basic example using numbers, then moves on to fractions, and finally covers variables. The concept of 'flipping' the base to remove the negative sign is emphasized. A practice problem is provided for viewers to solve, followed by a solution explanation.
