-72x^7
You Need to Know the Rules:
a%5E0+=+1
%28a%5Ep%29%5Eq+=+a%5E%28p%2Aq%29
root%28a%2Cp%29%2Aroot%28a%2Cq%29+=+root%28a%2Cp%2Aq%29
x%5Em%2Fx%5En=x%5E%28m-n%29
%28+x%5Em+%29%28+x%5En+%29+=+x%5E%28+m+%2B+n+%29******
root%28n%2C+%28x%2Fy%29%29+=+root%28n%2Cx%29%2Froot%28n%2Cy%29
%28xy%29%5En+=+x%5En%2Ay%5En
x^(1/n) = root%28n%2Cx%29 , x^(m/n) = root%28n%2Cx%29%29%5Em
