Simplifying Radicals and Square Roots

The video tutorial explains the concept of radicals, focusing on simplifying square roots. It introduces perfect squares and demonstrates how to simplify non-perfect square roots by identifying the largest perfect square factor. Several examples, including square roots of 18, 32, 40, 108, 48, 128, and 288, are used to illustrate the process.
