(1): "^-19" was replaced by "^(-19)".

Step  1  :

 1.1     10 = 2•5

(10)^-19 = (2•5)^(-19) = (2)^(-19) • (5)^(-19)

Equation at the end of step  1  :

  2 • ((2)(-19)•(5)(-19))

Step  2  :

Dividing exponents :

 2.1    2¹   divided by   2¹⁹   = 2^{(1 - 19)} = 2^(-18) = ¹/_2¹⁸

Final result :

      1                                       
  ————————— = 2.00000 • 10-19 
  (218•519)
