Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-2" was replaced by "^(-2)".

(2): "9.105" was replaced by "(9105/1000)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  9105
  ———— • ((2)(-2)•(5)(-2))
  1000

Step  2  :

            1821
 Simplify   ————
            200 

Equation at the end of step  2  :

  1821
  ———— • ((2)(-2)•(5)(-2))
  200 

Step  3  :

Multiplying exponents :

 3.1    2³  multiplied by  2²   = 2^{(3 + 2)} = 2⁵

Multiplying exponents :

 3.2    5²  multiplied by  5²   = 5^{(2 + 2)} = 5⁴

Final result :

    1821            
  ——————— = 0.09105 
  (25•54)
