Question

rewrite the expression without using a negative exponent.
-2y^{-4}
simplify your answer as much as possible.

Explanation:

Step1: Apply negative - exponent rule

According to the rule $a^{-n}=\frac{1}{a^{n}}$, for the term $y^{-4}$, we have $y^{-4}=\frac{1}{y^{4}}$.
So, $- 2y^{-4}=-2\times\frac{1}{y^{4}}$.

Step2: Simplify the expression

$-2\times\frac{1}{y^{4}}=-\frac{2}{y^{4}}$.

Answer:

$-\frac{2}{y^{4}}$
