lol , of course! any number's square root squared is the number! Take a look at these humorously simple examples:

it is now obvious that

you see, square root and squared cancel each other out! squared means x*x and square root means y*y=x but it its x squared square rooted, then its y*y=x in x*x, so y is obviously x!

Actually, this is quite easy once you think about it.
sqrt(x^2)
A number times itself must be .... positive!
The square root of a positive number gives us the original number, but it will be positive!
x = -2
sqrt((-2)^2) = sqrt(4) = 2
Does 2 = -2 ? No!
So we dub: sqrt(x^2) = | x | not
