One way to do this is what we call the L Hopital Rule, which is applied when the limit form after substitution is like 0/0 or infinity/infinity.
In such situations, the rule lets us differentiate both the top and numerator in the hope that the new value obtained is able to be calculated.

sorry is there any way to do this without the LHopital rule?
I did think of introducing the conjugate of the denominator at first and that was my first approach, but it led to a big mess.
If I manage to find a way, I will post a new one here.
EDIT: Found.
