Question

Plz help me with this

Answer 1

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

Explanation:

Using the rule of exponents

•
`(a^(m) )/(a^(n) )` ⇔
`(1)/(a^((n-m)) )` → n > m

Hence

`(y^(-5) )/(y^(-2) )` =
`(1)/(y^((-2-(-5))) )` =
`(1)/(y^(3) )`

Answer 2

Answer:
`\bold{(1)/(y^3)}`

Explanation:

`(y^(-5))/(y^(-2))\quad =(y^(-5+5))/(y^(-2+5))\quad =(y^0)/(y^3)\quad =\large\boxed{(1)/(y^3)}`
