 (1): "x4"   was replaced by   "x^4". 

Step  1  :

            x4
 Simplify   ——
            x2

Dividing exponential expressions :

 1.1    x⁴ divided by x² = x^{(4 - 2)} = x²

Equation at the end of step  1  :

   d
  —— • (3 • x2)
  dx

Step  2  :

             d
 Simplify   ——
            dx

Canceling Out :

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

Equation at the end of step  2  :

  1
  — • 3x2
  x

Step  3  :

Dividing exponential expressions :

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

Final result :

  3x
