The solution

You have entered [src]
log(x)           
------ + log(x)*3
log(3)           
$$\frac{\log{\left(x \right)}}{\log{\left(3 \right)}} + 3 \log{\left(x \right)}$$
log(x)/log(3) + log(x)*3
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. The derivative of is .

      So, the result is:

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

      1. The derivative of is .

      So, the result is:

    The result is:

  2. Now simplify:


The answer is:

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

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