How do I find the square root of 63?

Mostly, use a calculator. There is of course alogorithms to calculate the square root by hand to as many digits of accuacy you want, but generally that's very not efficent. You can roughly estimate the square root by logic. 7^2=49, 8^64, so the square root of 63 is between 7 and 8, and closer to 8 because it is only 1 number away from 8^2. You could estimate it linearly if you want as well. f(x)=(8-7)/(64-49) * (x - 49) + 7. so approximatly 7 and 14/15.
