Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-28" was replaced by "^(-28)".

(2): "9.11" was replaced by "(911/100)".

Step  1  :

 1.1     10 = 2•5

(10)^-28 = (2•5)^(-28) = (2)^(-28) • (5)^(-28)

Equation at the end of step  1  :

  911
  ——— • ((2)(-28)•(5)(-28))
  100

Step  2  :

            911
 Simplify   ———
            100

Equation at the end of step  2  :

  911
  ——— • ((2)(-28)•(5)(-28))
  100

Step  3  :

Multiplying exponents :

 3.1    2²  multiplied by  2²⁸   = 2^{(2 + 28)} = 2³⁰

Multiplying exponents :

 3.2    5²  multiplied by  5²⁸   = 5^{(2 + 28)} = 5³⁰

Final result :

     911                                      
  ————————— = 9.11000 • 10-28 
  (230•530)
