How to Simplify Radicals aka Simplifying Square Roots

The video tutorial introduces the concept of radicals and radicands, explaining that a radical is a square root sign and the number under it is called a radicand. It discusses the opposite nature of squaring and square roots, and focuses on simplifying radicals. Special numbers like 4, 9, 16, and 25 are highlighted for their ease of simplification. The tutorial provides examples of simplifying radicals, specifically radical 72 and radical 350, demonstrating the process of breaking down numbers into simpler radical forms.
