Use the Ratio Test or the Root Test to determine the values of x for which the series converges. Σ (2x)* k k = 1 Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The series converges only when (Type integers or simplified fractions.) <XS B. 1 The series converges only when SX 1 2 (Type integers or simplified fractions.) SX C. The series converges only when D. The series converges only when O E. The series converges only when x = <X (Type integers or simplified fractions.) - (Type integers or simplified fractions.) (Type an integer or a simplified fraction. Use a comma to separate answers as needed.)
