    Exclamation simple im sure

    i have u = x^(a+1) and need to find this in terms of x.
    does it involve square rooting this in terms of a +1?
    cheers

    For a\neq-1, raise both sides to the power of \frac1{a+1}. That is, do u^{1/(a+1)}=\left(x^{a+1}\right)^{1/(a+1)}.

    This would not be a square root unless a happens to equal 1.
