$\frac{1}{f} ^ 7$

#### Explanation:

I am assuming that you mean express with positive exponent.

In which case use the $\textcolor{b l u e}{\text{law of exponents}}$

$\textcolor{\mathmr{and} a n \ge}{\text{Reminder }} \textcolor{red}{| \overline{\underline{\textcolor{w h i t e}{\frac{a}{a}} \textcolor{b l a c k}{{a}^{-} m = \frac{1}{a} ^ m} \textcolor{w h i t e}{\frac{a}{a}} |}}}$

$\Rightarrow {f}^{-} 7 = \frac{1}{f} ^ 7$
