B 4 over y to the 3rd power
C y to the 3rd power over 4
D This expression is already simplified.

Answer 1

Please help

Answer 2

\[\large x^{-a} = \frac{1}{x^a}\] or the inverse is \(\huge \frac{1}{x^{-a}}\) = \(\huge x^a\)

`4 over y to the power of negative 3`
1) There is a fraction, where 4 is the numerator and \(y^{-3}\) is in the denominator.
\(\large \frac{4}{y^{-3}}\). Since a negative power is raised, it will be put to the numerator, where it would become: \(\large \frac{4y^3}{1}\) or \(\large 4y^3\)

Answer 3

so it is A

Answer 4

Yes
