Exponents and Their Properties

The video tutorial explains how to simplify expressions involving exponents, focusing on the rules for subtracting exponents when dividing like bases, applying powers to fractions, and converting negative exponents to positive ones. The process involves simplifying the expression step-by-step, ensuring all exponents are positive, and evaluating the final expression to reach the simplest form.
