Detail solution
  1. Differentiate term by term:

    1. The derivative of a constant times a function is the constant times the derivative of the function.

      1. Apply the power rule: goes to

      So, the result is:

    2. The derivative of a constant times a function is the constant times the derivative of the function.

      1. Let .

      2. Apply the power rule: goes to

      3. Then, apply the chain rule. Multiply by :

        1. Apply the power rule: goes to

        The result of the chain rule is:

      So, the result is:

    The result is:


The answer is:

The first derivative [src]
      b   
a - ------
       3/2
    2*x   
$$a - \frac{b}{2 x^{\frac{3}{2}}}$$
The second derivative [src]
 3*b  
------
   5/2
4*x   
$$\frac{3 b}{4 x^{\frac{5}{2}}}$$
The third derivative [src]
-15*b 
------
   7/2
8*x   
$$- \frac{15 b}{8 x^{\frac{7}{2}}}$$
