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

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