D) This expression is already simplified.

Respuesta :

Given
[tex] \frac{4}{ {y}^{ - 3} } [/tex]
Recall and apply this law of exponents,

[tex] \frac{1}{ {a}^{ - n} } = {a}^{n} [/tex]
[tex]4 \times \frac{1}{ {y}^{ - 3} } = 4 \times {y}^{3} [/tex]
[tex]4 \times \frac{1}{ {y}^{ - 3} } = 4 {y}^{3} [/tex]

The correct answer is A
