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

Step  1  :

 1.1     27 = 33

(27)^-1 = (3³)^(-1) = (3)^(-3)

Equation at the end of step  1  :

     1   
  ——————— ÷ 3
  (3)(-3) 

Step  2  :

                 1
 Divide  1  by  ——

  33
  ——
  3 

Step  3  :

            33
 Simplify   ——
            3 

Dividing exponents :

 3.1    3³   divided by   3¹   = 3^{(3 - 1)} = 3²
