(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  :

  35 • ((2)(-19)•(5)(-19))

Step  2  :

Dividing exponents :

 2.1    5¹   divided by   5¹⁹   = 5^{(1 - 19)} = 5^(-18) = ¹/_5¹⁸

Final result :

      7                                       
  ————————— = 3.50000 • 10-18 
  (219•518)
