Question

Modified true or false. If it is false, give a counterexample and briefly explain. If true, give a short proof.

(g) For each fixed k, and each a such that
0 < a < 1, the series Enka" converges
and thus, lim na"=0
(h) Suppose that fn(2)| ≤ Mn for ne N
where (M) is a sequence of positive
numbers. Then, the series Ef. (r) con-
verges uniformly when M,, converges.
