no, sorry for the confusion, it is only the quantity (y+2) under the square root
Solving these separately may be easier.
can you elaborate on that a little?

isnt it 2?
Correct. What is the limit of the last limit now?

it produces the indeterminate form 0/0.
Try evaluating the limit from the left and right.

can you help with lim e^(2x)-1/e^(x)-1 x->0
Did you ever solve the first one?
yes i got 1/4 as the limit
