Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-20" was replaced by "^(-20)".

(2): "1.494" was replaced by "(1494/1000)".

Step  1  :

 1.1     10 = 2•5

(10)^-20 = (2•5)^(-20) = (2)^(-20) • (5)^(-20)

Equation at the end of step  1  :

  1494
  ———— • ((2)(-20)•(5)(-20))
  1000

Step  2  :

            747
 Simplify   ———
            500

Equation at the end of step  2  :

  747
  ——— • ((2)(-20)•(5)(-20))
  500

Step  3  :

Multiplying exponents :

 3.1    2²  multiplied by  2²⁰   = 2^{(2 + 20)} = 2²²

Multiplying exponents :

 3.2    5³  multiplied by  5²⁰   = 5^{(3 + 20)} = 5²³

Final result :

     747                                      
  ————————— = 1.49400 • 10-20 
  (222•523)
