2 Jawaban

  • p = 1/3 + 1/9 + 1/27 + 1/81 + ...
    p = 1/3 ( 1 + 1/3 + 1/9 + 1/27 + 1/81 + ...)
    p = 1/3 ( 1 + (1/3 + 1/9 + 1/27 + 1/81 + ...))
    p = 1/3 ( 1 + p)
    3p = 1 + p
    2p = 1
      p = 1/2
  • P = 1/3 + 1/9 + 1/27 + 1/81 + ... p = 1/3 + 1/3( 1/3 + 1/8 + 1/27 +1/81+ ...) p = 1/3 + 1/3 p p-1/3 = 1/3 3/3p -1/3p = 1/3 2/3p = 1/3 6p = 3 p = 3/6 = 1/2
