Simplifying Square Roots with the Twin Method

The video tutorial by Miss Pair focuses on simplifying radicals. It begins with an introduction to radicals, explaining the radical symbol, index, and radicand. The tutorial then demonstrates simplifying radicals using perfect squares and introduces the prime factorization method. Examples include simplifying the square roots of 32 and 270, using factor trees and identifying perfect squares. The video emphasizes understanding the twin method and the importance of number sense and divisibility rules.
