∞∑n=0n1/n−1
∞∑n=0(1/n!)1/n
Hi. I am working on calculus now. While studying convergence test part, I ran into those problems... Wolfram alpha says they both diverges by comparison test. But I cannot think of the series to apply the comparison test... I tried ∑1/n or ∑1/n2 but failed..... Can you give me any clue?? I'd really appreciate your help.
