Answer

$c$

Work Step by Step

We start with the expression: $\frac{1}{c^{-1}}$. We rewrite using the division symbol: $1\div c^{-1}$ The negative exponent rule states that for every nonzero number $a$ and integer $n$, $a^{-n}=\frac{1}{a^n}$. We use this rule to rewrite the expression as $1\div\frac{1}{c^1}$ To divide by a fraction, we rewrite by multiplying by the reciprocal: $1\times c^1$ We multiply: $c$
