Question

hat variables are not zero.) -19c⁻⁹

Explanation:

Step1: Apply negative exponent rule

Recall $a^{-n}=\frac{1}{a^n}$, so rewrite $c^{-9}$:
$-19c^{-9} = -19 \times \frac{1}{c^9}$

Step2: Simplify the expression

Combine the terms into a single fraction:
$\frac{-19}{c^9}$

Answer:

$\frac{-19}{c^9}$ (or $-\frac{19}{c^9}$)
