Simplify $\left(c^{-1}\right)^2$ using the power of a power property: $\left(a^m\right)^n=a^{m\cdot n}$. In the expression, $m$ equals $-1$ and $n$ equals $2$

Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=c^{-2}$, $a^m=c^{-1}$, $a=c$, $a^m/a^n=\frac{5c^{-1}}{4c^{-2}}$, $m=-1$ e $n=-2$
