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): "2.421" was replaced by "(2421/1000)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

        2421
  0 -  (———— • ((2)(-19)•(5)(-19)))
        1000

Step  2  :

            2421
 Simplify   ————
            1000

Equation at the end of step  2  :

        2421
  0 -  (———— • ((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

Equation at the end of step  3  :

          2421  
  0 -  —————————
       (222•522) 

Step  4  :

Final result :

    -2421                                      
  ————————— = -2.42100 • 10-19 
  (222•522)
