1. The problem statement, all variables and given/known data This is from an online answer, and I don't understand the steps that it took. How did they go from the first red box to the second red box? 2. Relevant equations L'Hopital's rule Laws of exponents 3. The attempt at a solution I am really really confused. It looks like they took what e was raised to, and found the limit of that... but what rule allowed them to "Finally, plug in the original limit"?
