    The problem statement, all variables and given/known data
    Evaluate ##\lim_{a \rightarrow b} \frac{a^b-b^a}{a^a-b^b}##

    The attempt at a solution

    I applied L'Hospital's rule and to differentiate it, I took the help of logs.

    Put your code between two sets of ##

    What does ## mean?

    It means start code and end code. See I added them to your first post.
