Question

SOMEONE, PLEASE HELP!!!!!!

Answer 1

`(1)/(y^(3) )`

Explanation:

`(y^(-5))/(y^(-2))`

Apply exponent rule
`(x^a)/(x^b)=x^(a-b)`

`=y^(-5-\left(-2\right))`

Apply rule
`-\left(-a\right)=a`

`=y^(-5+2)`

Add/Subtract the numbers -5+2=-3

`=y^(-3)`

Apply exponent rule
`a^(-b)=(1)/(a^b)`

`=(1)/(y^3)`

Answer 2

I think its y^-3

Explanation:

Since y^-3/y^-2 are both negatives they would swap places to become positive - y^2/y^3

then using rules of exponents you would subtract the exponents witch would be y^-3
