log(3*x)^3
Detail solution
  1. Let .

  2. Apply the power rule: goes to

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

    1. Let .

    2. The derivative of is .

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

      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:

      The result of the chain rule is:

    The result of the chain rule is:


The answer is:

The graph
The first derivative [src]
     2     
3*log (3*x)
-----------
     x     
$$\frac{3 \log{\left(3 x \right)}^{2}}{x}$$
The second derivative [src]
3*(2 - log(3*x))*log(3*x)
-------------------------
             2           
            x            
$$\frac{3 \left(2 - \log{\left(3 x \right)}\right) \log{\left(3 x \right)}}{x^{2}}$$
The third derivative [src]
  /       2                  \
6*\1 + log (3*x) - 3*log(3*x)/
------------------------------
               3              
              x               
$$\frac{6 \left(\log{\left(3 x \right)}^{2} - 3 \log{\left(3 x \right)} + 1\right)}{x^{3}}$$
