Use the limit comparison test to determine whether n=8 8 (a) Choose a series br with terms of the form b n 8, An = lim lim nxx bp 818 n=8 4 2n+2 7n3-6n2 +8 an = n=8 2+2n4 converges or diverges. 1 = np and apply the limit comparison test. Write your answer as a fully simplified fraction. For (b) Evaluate the limit in the previous part. Enter as infinity and - as -infinity. If the limit does not exist, enter DNE. An lim nxx bn = 72 (c) By the limit comparison test, does the series converge, diverge, or is the test inconclusive? Diverges
