Question

Choose the correct simplification of the expression

Answer 1

\[\frac{ 4 }{ y ^{-3} }\]

Answer 2

With no hints as to what you're looking for, first glance says: \[4y^3\]

Answer 3

I just need to know how to simplify it, could you teach me?

Answer 4

There isn't much to simplify here, other than looking at the exponent on the y.

Answer 5

You can write \[\frac{1}{x^2}\] as \[x^{-2}\] Using the same logic, you have \[\frac{4}{y^{-3}}\] a negative exponent gives you \[4y^3\]

Answer 6

Ok I see. Thank you!

Answer 7

You're welcome.
