    Simplifying, once again

    I need to simplify this:


    (2b^-7c^4)^4
    _____________
    5^-1 b^2 c^6


    Here's my attempt:

    2^4 (b^7)^4 (c^4)^4
    ______________________
    .2 b^2 c^6


    16 b^-28 c^16
    ________________
    .2 b^2 c^6


    80c^10
    _______
    b^30



    Is this correct?


    ( ^ followed by a number represents an exponent)

    \frac{(2b^{-7}c^4)^4}{5^{-1}b^2c^6}

    Looks a bit easier to read, and if you want to know how to do it you can just place your mouse pointer over it and it shows you the code, and there are a few other places on this site somewhere that show you how to do it also.
