2 (a) Use the Comparison Test to show that the series En-1 4n3n²+3 converges. (You may use the fact that the series 1 converges if k > 1 and diverges if 0 < k < 1.) 3n (b) Use the Ratio Test to decide whether the series Σ=1 4√√n converges or diverges. (c) Use the Alternating Series Test to show that the series En-1 2-1 converges.
