Hi everyone.
I need to prove that if 0 < a < 1 , then the series converges.
I tried to use the limit test and the comparison test but I couldn't manage to.
Can someone give me a hint how to prove that?

Notice that . But, notice that since we may apply the series to the natural log to obtain that so what happens if ?
