Simplify the square root of an expression

The video tutorial explains how to simplify expressions involving exponents and square roots. It starts with variables X to the 4th and Y to the 16th, and demonstrates how to take the square root of each term separately. The square root of 121 is calculated as 11, and the power rule of exponents is applied to rewrite X to the 4th and Y to the 16th. The tutorial concludes with the final simplified expression: seven times eight X squared times Y to the 8th.
