%28%287%29sqrt+%283x%5E2y%29%29%5E11

I assume you mean this:

%28root%287%2C3x%5E2y%29%29%5E11

which you make on this site by putting this

 {{(root(7,3x^2y))^11}}

within triple braces, not double braces like above. 

----------------------------------------------------

Anyway, on this:

%28root%287%2C3x%5E2y%29%29%5E11,

we use this rule:

%28root%28INDEX%2CRADICAND%29%29%5EEXPONENT=RADICAND%5E%28%28EXPONENT%29%2F%28INDEX%29%29%29
