Question

-\frac{5a^{-2}b^{6}}{d^{5}}

Explanation:

Step1: Rewrite negative exponent

$a^{-2} = \frac{1}{a^2}$, so the expression becomes $\frac{-5b^6}{a^2d^5}$

Step2: Rearrange terms (optional, for clarity)

No further simplification possible, keep the form.

Answer:

$\frac{-5b^6}{a^2d^5}$ or $-\frac{5b^6}{a^2d^5}$
