Math tutorial for multiplying two radical expressions together by first simplifying

The video tutorial covers multiplying radical expressions, emphasizing that radicands can be multiplied if they share the same root index. It explains the importance of simplifying radicals before multiplication and provides examples, such as simplifying sqrt(4) to 2 and sqrt(x^2) to x. The tutorial concludes with a calculation example, resulting in 36x^2.

What is a necessary condition for multiplying radicands?
