A - bi would be the other complex zero.
When you take the sqrt when solving an equation you get a + and - solution.
(y^-5) / (y^-2)
Flip fraction and get rid of the negative from the exponents (you can do that!)
(y^2) / (y^5)
(y * y) / (y * y * y * y * y)
Cancel y's
1 / (y * y * y)
1 / (y^3)
That's your answer.
Have an awesome day! :)
