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): "2.45" was replaced by "(245/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  245   ((2)(-2)•(5)(-2)) 
  ——— • —————————————————
  100           2        

Step  2  :

            1         
 Divide  ———————  by  2
         (22•52)      

Multiplying exponents :

 2.1    2²  multiplied by  2¹   = 2^{(2 + 1)} = 2³

Equation at the end of step  2  :

  245    1 
  ——— • ———
  100   200

Step  3  :

            49
 Simplify   ——
            20

Equation at the end of step  3  :

  49    1 
  —— • ———
  20   200

Step  4  :

Final result :

   49            
  ———— = 0.01225
