I need help on these 5 math problems:

Find all x for which the power series converges. CO 20: 5r k=l3| (Use symbolic notation and fractions where needed. Give your answer as interval in the form (:2, :2). Use symbol no for innity, U for combining intervals, and appropriate type of parenthesis "If . j", "[", or "J" depending on whether the interval is open or closed.) x Find the interval of convergence of the power series. 00 (x + 1 )k *=0 5k (Use symbolic notation and fractions where needed. Give your answer as an interval in the form (*, *). Use the symbol co for infinity, U for combining intervals, and an appropriate type of parentheses "(", ")", "[", or "]" depending on whether the interval is open or closed.) X EFind the interval of convergence of the power series. C0 2 k(4x]k 15:0 (Use symbolic notation and fractions where needed. Give your answer as an interval in the form (as. as). Use the symbol on for innity, U for combining intervals, and an appropriate type of parentheses "t", ")", "L", or "J" depending on whether the interval is open or closed.) x E Find the radius of convergence and the interval of convergence of the series 22:\" 3. (Use symbolic notation and fractions where needed. For the second part of the question, give your answer as an interval in the form (\"U\"). Use the symbol on for innity, U for combining intervals, and an appropriate type of parenthesis "(",")" "L" or "j" depending on whether the interval is open or closed.) x Find all x for which the power series converges. (W k (x 2) E (2k)! (Use symbolic notation and fractions where needed. Give your answer as interval in the form (:2, :2}. Use symbol oo for innity, U for combining intervals, and appropriate type of parenthesis "( . ]\
