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)".

Step  1  :

            4
 Simplify   —
            9

Equation at the end of step  1  :

  4
 (—)-1) ÷ 2
  9

Step  2  :

 2.1     4 = 22

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

Equation at the end of step  2  :

  (2)(-2)
  ——————— ÷ 2
  (3)(-2)

Step  3  :

         (2)(-2)      
 Divide  ———————  by  2
         (3)(-2)      

Multiplying exponents :

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

Final result :

  9           
  — = 1.12500
