Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

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

(2): "8.65" was replaced by "(865/100)".

Step  1  :

 1.1     10 = 2•5

(10)^-1 = (2•5)^(-1) = (2)^(-1) • (5)^(-1)

Equation at the end of step  1  :

  865
  ——— • ((2)(-1)•(5)(-1))
  100

Step  2  :

            173
 Simplify   ———
            20 

Equation at the end of step  2  :

  173
  ——— • ((2)(-1)•(5)(-1))
  20 

Step  3  :

Multiplying exponents :

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

Multiplying exponents :

 3.2    5¹  multiplied by  5¹   = 5^{(1 + 1)} = 5²

Final result :

  173           
  ——— = 0.86500 
  200
