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): "2.94" was replaced by "(294/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  294
  ——— • ((2)(-19)•(5)(-19))
  100

Step  2  :

            147
 Simplify   ———
            50 

Equation at the end of step  2  :

  147
  ——— • ((2)(-19)•(5)(-19))
  50 

Step  3  :

Multiplying exponents :

 3.1    2¹  multiplied by  2¹⁹   = 2^{(1 + 19)} = 2²⁰

Multiplying exponents :

 3.2    5²  multiplied by  5¹⁹   = 5^{(2 + 19)} = 5²¹

Final result :

     147                                      
  ————————— = 2.94000 • 10-19 
  (220•521)
