Hi,

I was wondering how I would convert $\displaystyle \frac{1}{3x^3} $ and $\displaystyle \frac{1}{3x} $ to "power form". For example $\displaystyle \frac{2}{x^3}$ would be $\displaystyle 2x^-3$ but when I try the same logic with the first two, $\displaystyle \frac{1}{3x^3} $ would become $\displaystyle {3x^-3} $ but that's wrong? When 1 is the numberator I seem to get them wrong.
