I am having some challenges understanding this problem, I was wondering if someone could help me understand how to approach it?
thank you in advance
L (a) = lim as x -> 0 of (a^x -1)/x
Exists or all a > 0. Assume also that lim x -> 0 a^x =1.
Using limit rules, prove that:
L(ab) = L(a) + L(b)
for a,b> 0
Hint: (ab)^x -1 = a^x(b^x - 1) + (a^x - 1)
