The video tutorial explains how to convert between radical expressions and expressions with rational exponents. It provides guidelines and examples for both directions of conversion, including simplification and recognizing inverse relationships. The tutorial aims to help students understand the relationship between radicals and rational exponents, and how to apply these concepts in mathematical expressions.

What is the main concept discussed in the introduction of the video?
