Reformatting the input :

Changes made to your input should not affect the solution:

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

Step  1  :

            4
 Simplify   —
            9

Equation at the end of step  1  :

  4
 (—)-1
  9

Step  2  :

 2.1     4 = 22

(4)^-1 = (2²)^(-1) = (2)^(-2)  2.2     9 = 3² (9)^-1 = (3²)^(-1) = (3)^(-2)

Final result :

  1 • 32
  ——————
  1 • 22
