Question

Choose the correct simplification of the expression 4 over y to the power of negative 3.

A) 4y^3

B) 4 over y to the 3rd power

C) y to the 3rd power over 4

D) This expression is already simplified.

Answer 1

it is A

Explanation:

Answer 2

Given

`\frac{4}{ {y}^( - 3) }`
Recall and apply this law of exponents,


`\frac{1}{ {a}^( - n) } = {a}^(n)`

`4 * \frac{1}{ {y}^( - 3) } = 4 * {y}^(3)`

`4 * \frac{1}{ {y}^( - 3) } = 4 {y}^(3)`

The correct answer is A
