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
  — • x2
  x

Step  2  :

Dividing exponential expressions :

 2.1    x² divided by x¹ = x^{(2 - 1)} = x¹ = x

Final result :

  x
