Detail solution
  1. Let .

  2. Apply the power rule: goes to

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

    1. Differentiate term by term:

      1. Apply the power rule: goes to

      2. The derivative of the constant is zero.

      The result is:

    The result of the chain rule is:

  4. Now simplify:


The answer is:

The graph
The first derivative [src]
     1      
------------
         2/3
3*(x + 1)   
$$\frac{1}{3 \left(x + 1\right)^{\frac{2}{3}}}$$
The second derivative [src]
    -2      
------------
         5/3
9*(1 + x)   
$$- \frac{2}{9 \left(x + 1\right)^{\frac{5}{3}}}$$
The third derivative [src]
      10     
-------------
          8/3
27*(1 + x)   
$$\frac{10}{27 \left(x + 1\right)^{\frac{8}{3}}}$$
