Solution - Power equations

Step  1  :

             d
 Simplify   ——
            dx

Canceling Out :

 1.1    Canceling out d as it appears on both sides of the fraction line

Equation at the end of step  1  :

     1
  (((— • s) • e) • n) • x3
     x

Step  2  :

Dividing exponential expressions :

 2.1    x³ divided by x¹ = x^{(3 - 1)} = x²

Final result :

  x2sen
