34 views and no solutions? Come on physicsforums, you're making me think this is a beta board and I should go look to more able forums.

I'm still stumped. Why don't you let me off and show the solution :D :D ;D

Let (an) be a sequence of positive real numbers, decreasing and the sum of whose terms is infinite. Prove that the series whose general term is min(an, 1/n) is also divergent. I'm sorry but I'm no where with it. Could someone tell me if this is too difficult? Thanks!

Let a,b>1 be integers such that for all n>0 we have a^n-1|b^n-1. Then b is a natural power of a. I can't find a solution.
