Understanding Square Roots and Integers

This video tutorial explains how to find two consecutive integers between which the square root of a given number lies. The process involves identifying two consecutive perfect squares surrounding the radicand, extracting their principal roots, and determining the integers. Two examples are provided: finding the consecutive integers for the square roots of 21 and 89. The video concludes with a summary of the method.
