   note:  2, 19, 71 are all prime numbers

   math using MathBabbler's prime number functions...
      a)  19 - 2 = reverse_digits(71)
      b)  mult_digits(19) - mult_digits(71) = 2
      c)  sum_digits(19) - sum_digits(71) = 2
      d)  2^sqrt(mult_digits(19)) = sum_digits(71)

   observe...
      reverse_digits(71) = 17
      mult_digits(19) = 1 * 9 = 9
      mult_digits(71) = 7 * 1 = 7
      sum_digits(19) = 1 + 9 = 10
      sum_digits(71) = 7 + 1 = 8
