log (x)

$$\frac{x}{\log{\left(x \right)}^{2}}$$

x/log(x)^2

Detail solution

Apply the quotient rule, which is:

$\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$

$f{\left(x \right)} = x$ and $g{\left(x \right)} = \log{\left(x \right)}^{2}$ .

To find $\frac{d}{d x} f{\left(x \right)}$ :
1. Apply the power rule: $x$ goes to $1$
To find $\frac{d}{d x} g{\left(x \right)}$ :
1. Let $u = \log{\left(x \right)}$ .
2. Apply the power rule: $u^{2}$ goes to $2 u$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \log{\left(x \right)}$ :
  1. The derivative of $\log{\left(x \right)}$ is $\frac{1}{x}$ .
  The result of the chain rule is:
  
  $\frac{2 \log{\left(x \right)}}{x}$
Now plug in to the quotient rule:

$\frac{\log{\left(x \right)}^{2} - 2 \log{\left(x \right)}}{\log{\left(x \right)}^{4}}$
Now simplify:

$\frac{\log{\left(x \right)} - 2}{\log{\left(x \right)}^{3}}$

The answer is:

$\frac{\log{\left(x \right)} - 2}{\log{\left(x \right)}^{3}}$
