    Well, the answer (if I'm not stupid) is
    14316558.653
    I'm not sure exactly how else you teacher wants you to write the number though?
    I doubt that can be turned into a neat fraction or anything, do you remember anything else she said?

    I'm not clear if you mean
    ((2^32)/300) + 1 or
    (2^(32/300)) + 1
    Assuming you mean:
    (2^(32/300)) + 1
    Remember that:
    √x = x^(1/2)
    √(x^2) = x^(2/2) = x
    So for any value raised to a power that is a fraction, you can rewrite it as a root, where the denominator is the degree of the root (square, cubic, etc), and the numerator is the power of the value inside the root. (I'm bad at explaining things )
    So for your problem,
    (2^32/300)+1,
    =(2^(8/75))+1
    = + 1
    Maybe that's what she wanted, because as YoHoJo pointed out, that's not likely to turn out a whole number or nice fraction.

    If you meant the first one [((2^32)/300) + 1], then you basically need to get 300 as a power of two (dunno if you have learned this yet)...
    300 = 2^x
    x = log2(300)
    = 8.289
    ((2^32)/300) + 1
    = ((2^32)/(2^8.289))+1
    = 2^(32-8.289) + 1
    = 2^23.711 + 1
    Although this is probably even more decimal-y than the other one

    (2^(32 / 300)) + 1 = 2.07673757

    ------------------------------------------

    ((2^32) / 300) + 1 = 14316558.7

    ------------------------------------------



    There are couple different ways to calculate it... Don't know what you are looking for exactly...

    just didn't know if the exponent was 32 or 32/300 ...

    Would of been easier if you had more details...
