You can put this solution on YOUR website!
%28x%5E-2%2Bx%5E-1%29%5E3
%281%5E%22%22%2Fx%5E2%2B1%5E%22%22%2Fx%5E%22%22%29%5E3
That has no negative indices (We only called them 'exponents' in the olden days,
and 'index' (plural 'indices') referred to n for the nth root).
You can go further and get
%28x+%2B+1%29%5E3%2Fx%5E6 if you like.
