what problems are you having with changing these forms to forms with powers? if you don't understand the manipulations i or some other users do, it is in your best interest to ask. based on the problems you've received help with thus far, you should not be having a problem with this.

$\displaystyle h(x) = x^2 + \frac 1{7x} = x^2 + \frac 17x^{-1}$
