The video tutorial explains how to divide expressions with rational exponents, which are essentially fractional exponents. It begins with an introduction to the concept and then demonstrates the process through two example problems. The first example involves simplifying an expression with a single variable, while the second example includes two variables. The tutorial covers the rules for dividing exponents, finding common denominators, and converting between rational exponents and radicals. It also addresses the importance of not having radicals in the denominator and how to rationalize them.
