Hello

Sure! Say you have x^-1 that would be

$1\over x$ if you have x^2 you would get $1\over x^2$ and so on.. but if you have say 

$2x^{-2}$you would get $2 \over x^2$

if you have a fraction that is negative for example $-1\over 2$you would get

$1 \over \sqrt{x}$ , i'm assuming you've already learnt the fraction indice laws.
