Approximate the square root

The video tutorial explains the concept of squared numbers and how to approximate square roots for numbers that are not perfect squares. It provides examples using the numbers 35 and 17, showing how to find approximate values by comparing them to nearby perfect squares. The tutorial emphasizes that these approximations are not exact but provide a close estimate.
