Simplify radical expressions by finding quotient, fourth root

The video tutorial explains how to simplify a mathematical expression by dividing and finding the fourth root. It starts with rewriting the expression as a radical, then divides 162 by 2 to get 81. The tutorial demonstrates finding the fourth root of 81, which is 3, and then discusses taking the fourth root of variables X and Y. The process concludes with simplifying the expression by extracting roots and understanding the placement of terms.
