Square Roots and Prime Factorization

The video tutorial covers the process of finding square roots using the prime factorization method. It begins with a recap of the previous class and then demonstrates the method on several numbers: 729, 400, 1764, 4096, and 7744. Each example is broken down step-by-step, showing how to divide the number into its prime factors and then determine the square root. The tutorial concludes with a brief summary and a look ahead to the next class.
