Answer: Use the result of Exercise 61 to prove that if the nonnegative series converges
Chapter 9, Problem 62(choose chapter or problem)
Use the result of Exercise 61 to prove that if the nonnegative series \(\sum_{n=1}^{\infty} a_{n}\) converges, then so does the series \(\sum_{n=1}^{\infty}a_n^{\ 2}\)?.
Text Transcription:
sum_n=1 ^infty a_n
sum_n=1 ^infty a_n ^2
