@Raphael, I think they are and if the question is about taking those limits, it's not a question for CS.SE. But those answers were incorrect, by the time gnasher729 wrote the comment.

Agreed. Suresh, please read the reference question. If computing the limit is beyond you, [math.SE] would be the place to get help with that. Good luck!

That reference section could do with a section what happens when you take the logarithm on both sides. PS. The question is a nice example where drawing a graph and drawing conclusions will absolutely give you the wrong answer.
