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

Step  1  :

 1.1     1000 = 23•53

(1000)^-2 = (2³•5³)^(-2) = (2)^(-6) • (5)^(-6)

Equation at the end of step  1  :

         343       
  ————————————————— ÷ 3
  ((2)(-6)•(5)(-6)) 

Step  2  :

                     1   
 Divide  343  by  ———————
                  (26•56)

Equation at the end of step  2  :

  (73•26•56) 
  ——————————
      3     

Step  3  :

            (73•26•56) 
 Simplify   ——————————
                3     

Final result :

  (73•26•56)                                  
  —————————— = 1.14333 • 108
