Solution - Power equations

Step  1  :

Equation at the end of step  1  :

      d
  (((—— • c) • o) • s) • (3•5x5)
     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
  (((— • c) • o) • s) • (3•5x5)
     x

Step  3  :

Dividing exponential expressions :

 3.1    x⁵ divided by x¹ = x^{(5 - 1)} = x⁴

Final result :

  15x4cos
