Understanding Square Roots Using Factor Trees

This video tutorial explains how to find square roots using a factor tree method. It begins with basic examples like the square roots of 9 and 25, demonstrating the process of creating a factor tree and identifying prime numbers. The tutorial then covers more complex examples, such as the square roots of 12 and 50, showing how to handle cases where not all factors form pairs. Finally, it concludes with the square root of 36, summarizing the method and encouraging viewers to subscribe for more math and science content.
