Solution - Power equations

Step  1  :

Equation at the end of step  1  :

     d                  
  ((—— • 4) • (x5)) +  5x4
    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                
  ((— • 4) • x5) +  5x4
    x                

Step  3  :

Dividing exponential expressions :

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

Equation at the end of step  3  :

  4x4 +  5x4

Step  4  :

Final result :

  9x4
