Solution - Power equations

Step  1  :

             x
 Simplify   ——
            x3

Dividing exponential expressions :

 1.1    x¹ divided by x³ = x^{(1 - 3)} = x^(-2) = ¹/_x²

Equation at the end of step  1  :

     3       1
  ——————— • ——
  (x - 3)   x2

Step  2  :

              3  
 Simplify   —————
            x - 3

Equation at the end of step  2  :

    3      1
  ————— • ——
  x - 3   x2

Step  3  :

Final result :

        3     
  ————————————
  x2 • (x - 3)
