(1): "^-2" was replaced by "^(-2)".

Step  1  :

             8 
 Simplify   ———
            125

Equation at the end of step  1  :

   (8
 (———)-2) ÷ 3
  125

Step  2  :

 2.1     8 = 23

(8)^-2 = (2³)^(-2) = (2)^(-6)  2.2     125 = 5³ (125)^-2 = (5³)^(-2) = (5)^(-6)

Equation at the end of step  2  :

  (2)(-6)
  ——————— ÷ 3
  (5)(-6)

Step  3  :

         (2)(-6)      
 Divide  ———————  by  3
         (5)(-6)      

Final result :

   56            
  ——— = 81.38021
