Question

rewrite the expression without using a negative exponent. -3y^{-5} simplify your answer as much as possible.

Explanation:

Step1: Apply negative - exponent rule

Recall the rule $a^{-n}=\frac{1}{a^{n}}$. For the term $y^{-5}$, we have $y^{-5}=\frac{1}{y^{5}}$.
So, $- 3y^{-5}=-3\times\frac{1}{y^{5}}$.

Step2: Simplify the expression

$-3\times\frac{1}{y^{5}}=-\frac{3}{y^{5}}$.

Answer:

$-\frac{3}{y^{5}}$
