(3^x*log(x))/log(3)

Detail solution

The derivative of a constant times a function is the constant times the derivative of the function.
1. Apply the product rule:
  
  $\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}$
  
  $f{\left(x \right)} = 3^{x}$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
  1. $\frac{d}{d x} 3^{x} = 3^{x} \log{\left(3 \right)}$
  $g{\left(x \right)} = \log{\left(x \right)}$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
  1. The derivative of $\log{\left(x \right)}$ is $\frac{1}{x}$ .
  The result is: $3^{x} \log{\left(3 \right)} \log{\left(x \right)} + \frac{3^{x}}{x}$
So, the result is: $\frac{3^{x} \log{\left(3 \right)} \log{\left(x \right)} + \frac{3^{x}}{x}}{\log{\left(3 \right)}}$
Now simplify:

$3^{x} \log{\left(x \right)} + \frac{3^{x}}{x \log{\left(3 \right)}}$

The answer is:

$3^{x} \log{\left(x \right)} + \frac{3^{x}}{x \log{\left(3 \right)}}$
