Question

Rewrite the expression in the form y^n

Answer 1

`y^6`

Explanation:

The applicable rules of exponents are ...

`y^ay^b=y^(a+b)\\\\(1)/(y^(-a))=y^a`

Using these rules, you can write the expression as ...

`(y^(-7))/(y^(-13))=y^(-7-(-13))=y^6`

Answer 2

`$ y^6 $`

Explanation:

`$ (a^b)/(a^c) = a^(b - c) $`

Using this rule we have:

`$ (y^(-7))/(y^(-13))  = y^(-7 -(-13)) = y^6$`
