log(3*x)
--------
 log(5) 
$$\frac{\log{\left(3 x \right)}}{\log{\left(5 \right)}}$$
d /log(3*x)\
--|--------|
dx\ log(5) /
$$\frac{d}{d x} \frac{\log{\left(3 x \right)}}{\log{\left(5 \right)}}$$
Detail solution
  1. The derivative of a constant times a function is the constant times the derivative of the function.

    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:

    So, the result is:


The answer is:

The graph
The first derivative [src]
   1    
--------
x*log(5)
$$\frac{1}{x \log{\left(5 \right)}}$$
The second derivative [src]
   -1    
---------
 2       
x *log(5)
$$- \frac{1}{x^{2} \log{\left(5 \right)}}$$
The third derivative [src]
