## Homework Statement

(2+y^2)/sqrt(4+y^4) as y goes to positive infinity

## Homework Equations

## The Attempt at a Solution

I divided it out by y^2 to get

lim y-> inf+ (2+y^2)/y^2 = 1 and the bottom lim y -> inf+ sqrt(4+y^4)/y^2 I can't solve..

by the way, I can't use L'hopitals rule

thanks!!
