Prime Factorization and Radical Simplification

The video tutorial explains how to simplify radicals with non-perfect square radicands and variables. It begins with the prime factorization of 96 to identify perfect square factors, then demonstrates simplifying the square root of 96x⁹y⁴. The process involves grouping factors to find perfect squares and simplifying the expression. The tutorial then shifts to simplifying the cube root of -2 times 54x⁴, using a similar method to find perfect cube factors. The video concludes by highlighting the usefulness of prime factorization in simplifying radicals.
