Step-by-step explanation:

[tex]\frac{1}{y^3}[/ tex]

Step-by-step explanation:

When we write a number raised to -1 (except zero), we mean that we are writing its inverse.

It can be written in two ways

[tex] a ^ -1[/ tex]=[tex]\ frac {1} {a} [/ tex]

Applies the same when it is raised to another negative number

So if we have

[tex] y ^ -3 [/ tex], we can rewrite it as

[tex]\frac{1}{y^3}[/ tex]

[tex] y ^ -3 [/ tex] = [tex] \ frac {1}{y^3} [/ tex]
