Step  1  :

 1.1     1000 = 23•53

(1000)^-1 = (2³•5³)^(-1) = (2)^(-3) • (5)^(-3)

Equation at the end of step  1  :

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

Step  2  :

                     1   
 Divide  343  by  ———————
                  (23•53)

Equation at the end of step  2  :

  (73•23•53) 
  ——————————
      3     

Step  3  :

            (73•23•53) 
 Simplify   ——————————
                3     

Final result :

  (73•23•53)                                  
  —————————— = 1.14333 • 105
