Can somebody tell me if this is the right answer. Solve 8 is to 64 as 2 is to x, (x1)^2=64 (8)^2=64 is

What does x equal?
Why are you squaring anything? 
Is 64 the right answer yes or no, to the question I put up there.

x does not equal 64.
8 / 64 = 2 / x
Cross multiply and solve for x.
8x = 128
x = 128/8
x = 16
