Some people gave you the correct answer. But what you need to know is that the sq root of some number (number A) is the number (number B) that multiplied by itself that equals number A. So B is the sq. root of A if B*B=A.
If you don't have a calculator to tell you, usually you have to figure it out by trial and error.
64 is kind of easy, because we should know from our multiplication tables that 8*8=64. But what if you had to find the square root of 256? You have to take a guess and see what happens. We know 10*10=100, and 20*20=400. So the sq root of 256 must be between them. So start with, say 15*15, and then go from there. (You can do the same thing using division if you prefer....divide 256 by 15 and see if it is 15, and so on.)
By the way, the sq. root of 256 is 16.

64 is the square of a number. You want to know the square root. In other words, what number, times itself, equals 64?
8 because 8*8 is 64.

64 = 8*8 = 8^2
Take square roots:
sqrt(64) = sqrt(8^2) = 8
