This instructor in this video, Sal Khan, discusses how to use exponent rules to simply radicals or square roots. Mr. Khan uses computer software (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Aw...ard in Education.[more]

Instructor uses a white board to model simplifying square roots into simplest radical form. Examples include perfect square roots, leading coefficient of one, and a leading coefficient other than one. (7:53)

This lesson begins with a table for the viewer to complete while the video is paused. Then, the instructor explains what should have been discovered through the completion of this table. Then, the instructor uses a variety of examples to explain ho...w to simplify various types of radicals.[more]

In this video Sal Khan focuses on demonstrating how to simplify square roots. The video has small writing and should be opened to 'full screen' to view. (05:36)

Video of a whiteboard demonstration on calculating square roots by hand, breaking down "72" (not a simple square) into a factor tree, then the prime numbers and simplifying. (1:22)
