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): "4.156" was replaced by "(4156/1000)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  4156
  ———— • ((2)(-2)•(5)(-2))
  1000

Step  2  :

            1039
 Simplify   ————
            250 

Equation at the end of step  2  :

  1039
  ———— • ((2)(-2)•(5)(-2))
  250 

Step  3  :

Multiplying exponents :

 3.1    2¹  multiplied by  2²   = 2^{(1 + 2)} = 2³

Multiplying exponents :

 3.2    5³  multiplied by  5²   = 5^{(3 + 2)} = 5⁵

Final result :

    1039            
  ——————— = 0.04156 
  (23•55)
