Simplifying Square Roots and Radicals

This video tutorial covers the process of simplifying radicals, focusing on square roots. It begins with an introduction to the importance of understanding radicals in algebra. The video explains the definition of square roots and demonstrates the tree method for simplifying radicals through examples, including the square roots of 25, 20, and 50. The tutorial emphasizes finding pairs of numbers that multiply to the number under the radical and extracting them to simplify the expression.
