Calculus problem, step by step?

Could someone explain to me step by step

of this problem? I'm trying to understand how to simplify this problem but I keep coming to the conclusion that the limit = 0 because both numerator and denominator are 0 and I'm certain that's not correct.

I'm trying to look at a problem and its answer and prove that that's the answer by filling in the steps in between

Update:

Can't find a way to solve
