3. Let {a,,} be a sequence. (a) Suppose an : (3\". Determine whether {an} converges or diverges with justication. If it converges, provide the limit. l}nn (b) Suppose an = e( . Determine whether {an} converges or diverges with justication. If it converges, provide the limit. (c) Suppose 1 an = m: where or E R. Determine whether {on} converges or diverges with justication. If it con verges, provide the limit. (Hint: consider the cases where o: > 0, o:
