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): "2.913" was replaced by "(2913/1000)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  2913
  ———— • ((2)(-20)•(5)(-20))
  1000

Step  2  :

            2913
 Simplify   ————
            1000

Equation at the end of step  2  :

  2913
  ———— • ((2)(-20)•(5)(-20))
  1000

Step  3  :

Multiplying exponents :

 3.1    2³  multiplied by  2²⁰   = 2^{(3 + 20)} = 2²³

Multiplying exponents :

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

Final result :

     2913                                     
  ————————— = 2.91300 • 10-20 
  (223•523)
