Detail solution
  1. Differentiate term by term:

    1. Let .

    2. Apply the power rule: goes to

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

      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 the constant is zero.

        The result is:

      The result of the chain rule is:

    4. The derivative of the constant is zero.

    The result is:

  2. Now simplify:

-------------
          3/2
(-3 + 2*x)   
$$- \frac{1}{\left(2 x - 3\right)^{\frac{3}{2}}}$$
The third derivative [src]
      3      
-------------
          5/2
(-3 + 2*x)   
$$\frac{3}{\left(2 x - 3\right)^{\frac{5}{2}}}$$
