Learning how to use prime factorization to simplify a radical expression

The video tutorial explains the concept of square roots, focusing on what number multiplied by itself results in a given number or variable squared. It introduces the use of factor trees to break down numbers and variables, demonstrating how to decompose 81 and X squared into their factors. The tutorial then explains the process of taking square roots by identifying pairs of factors and calculating the square root of 81 and X squared, resulting in 9X.

Explain the process of finding the square root of 81 using factorization.

What is the result of multiplying 3 by itself and X by itself?
