Use the limit comparison test to determine if ∑n = 1∞6 n45+3 n+5 n14−4 converges or diverges, and justify your answer. Answer Attempt 1 out of 3 Apply the comparison test with the series ∑n = 1∞1 np where p = . If an = 6 n45+3 n+5 n14−4 and bn = 1 np, then limn→∞an bn = . Since an, bn > 0 and the limit is a finite and positive (non-zero) number, the limit comparison test applies. ∑n = 1∞1 np since a p-series will if and only if . Therefore, ∑n = 1∞6 n45+3 n+5 n14−4

Use the limit comparison test to determine if n = 1 6 n 4 5 + 3 n + 5 n 1 4 4 converges or diverges, and justify your answer. Answer Attempt 1 out of 3
Apply the comparison test with the series n = 1 1 n p where p = . If a n = 6 n 4 5 + 3 n + 5 n 1 4 4 and b n = 1 n p , then lim n a n b n = . Since a n , b n > 0 and the limit is a finite and positive (non-zero) number, the limit comparison test applies. n = 1 1 n p since a p-series will if and only if .Therefore, n = 1 6 n 4 5 + 3 n + 5 n 1 4 4
