    If you take the square root of the square root of x, and that = x ^ a what does a equal?

    I don't understand your statement. You are saying what is sqrt{x^a}?

    Answer: x^(a/2).

    If you take the square root of the square root of x, you have sqrt(x) or x^(1/2)

    and that = x ^ a

    =>x^(1/2)=x ^ a ........if base same, exponents are same too

    =>a=1/2

    Cool but is my answer incorrect?
    I stated the answer to be x^(a/2). If wrong, why am I wrong?

    your mistake is at very beginning:
    read carefully: If you take the square root of the square root of x =>sqrt(x)
    , and that is equal to x ^ a

    =>sqrt(x) =x ^ a

    but you did this: sqrt(x ^ a) which is not what is given
