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

Step  1  :

            v2
 Simplify   ——
            3 

Equation at the end of step  1  :

       v2
  (4 • ——) • v(-1)
       3 

Step  2  :

Multiplying exponential expressions :

 2.1    v² multiplied by v^(-1) = v^{(2 + (-1))} = v¹ = v

Final result :

  4v
