How To Estimate Square Roots
In order to estimate square roots, one must first list out a few perfect squares and their corresponding number: Numbers such as 12, 22, 32, 42, 52, 62, and 72, which correspond with 1, 4, 9, 16, 25, 36, and 49. Once you have these written out you can begin to estimate what the square root will be close to. For example, take the square root of 48, which is not easily done in mathematics. But using the numbers listed before we can find an estimate. 48 is one away from 49. So the answer to the square root of 48 would be around 7.
