Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

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

(2): "3.943" was replaced by "(3943/1000)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  3943
  ———— • ((2)(-19)•(5)(-19))
  1000

Step  2  :

            3943
 Simplify   ————
            1000

Equation at the end of step  2  :

  3943
  ———— • ((2)(-19)•(5)(-19))
  1000

Step  3  :

Multiplying exponents :

 3.1    2³  multiplied by  2¹⁹   = 2^{(3 + 19)} = 2²²

Multiplying exponents :

 3.2    5³  multiplied by  5¹⁹   = 5^{(3 + 19)} = 5²²

Final result :

     3943                                     
  ————————— = 3.94300 • 10-19 
  (222•522)
