calculus - How do I approach solving this indeterminate limit? limlimitshto0frac1hlnleft(frac2+h2right)

Disclaimer: I am a middle aged adult learning Calculus. This is not a student posting his homework assignment. Thank humanity for this great forum!



limh01hln(2+h2)



1) Can't directly sub the h. So, normally you reduce and cancel. Can you point me in the right direction? The directions say "manipulate the expression so L'Hopital's is used" I think L'hopital's is involved. Just not sure how to deal with the 1h

2) Also, any tips on the one above? If k is a positive integer, what is the limit above?



Thanks for any guidance.
