Reformatting the input :

Changes made to your input should not affect the solution:

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

Step  1  :

            49
 Simplify   ——
            9 

Equation at the end of step  1  :

  49
 (——)-1
  9 

Step  2  :

 2.1     49 = 72

(49)^-1 = (7²)^(-1) = (7)^(-2)  2.2     9 = 3² (9)^-1 = (3²)^(-1) = (3)^(-2)

Final result :

  1 • 32
  ——————
  1 • 72
