    64 = 23x

    You would need to do 64/23.

    This would get you approximately 2.78.

    So your answer would either be A. x=2.5 or D. x=3.

    I'm pretty sure it would be D though because you are more likely to round up.

    If the question is asking this:64=2^3x

    The answer is: x=2

    64=2x2x2x2x2x2 = 2^6

    2^3x = 2^6

    X=2
