Simplifying Expressions with Exponents

The video tutorial explains how to simplify mathematical expressions involving fractions and exponents. It covers three main expressions, demonstrating the use of exponent rules such as multiplying and dividing powers, and converting negative exponents to positive. Each expression is broken down step-by-step, showing how to handle powers raised to powers and how to simplify the resulting fractions.
