Question

expressions with negative and zero exponents (note that variables are not zero.)
$14c^{-2}$

Explanation:

Step1: Apply negative exponent rule

Recall $a^{-n}=\frac{1}{a^n}$, so $c^{-2}=\frac{1}{c^2}$.

Step2: Rewrite the original expression

Substitute $c^{-2}$ into $14c^{-2}$:
$14 \times \frac{1}{c^2} = \frac{14}{c^2}$

Answer:

$\frac{14}{c^2}$
