It's best to use a calculator for this.

Without a calculator, several methods exist; for example, just try out different numbers. Since 2 squared is 4 and 3 squared is 9, the square root of 8 must be between those too. Continue trying with some other numbers - for example, 2.5 squared is 6.25, so you have to go a bit higher.

More efficient (i.e., faster) methods exists as well, but they are all based on iterative procedures - that is, repeating a series of operations over and over again, until you get close enough to the desired result.
