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): "3.25" was replaced by "(325/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  325
  ——— • ((2)(-2)•(5)(-2))
  100

Step  2  :

            13
 Simplify   ——
            4 

Equation at the end of step  2  :

  13
  —— • ((2)(-2)•(5)(-2))
  4 

Step  3  :

Multiplying exponents :

 3.1    2²  multiplied by  2²   = 2^{(2 + 2)} = 2⁴

Final result :

   13           
  ——— = 0.03250
