$$3^{\frac{1}{\log{\left(x + 1 \right)}}}$$

3^(1/log(x + 1))

Detail solution

Let $u = \frac{1}{\log{\left(x + 1 \right)}}$ .
$\frac{d}{d u} 3^{u} = 3^{u} \log{\left(3 \right)}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \frac{1}{\log{\left(x + 1 \right)}}$ :
1. Let $u = \log{\left(x + 1 \right)}$ .
2. Apply the power rule: $\frac{1}{u}$ goes to $- \frac{1}{u^{2}}$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \log{\left(x + 1 \right)}$ :
  1. Let $u = x + 1$ .
  2. The derivative of $\log{\left(u \right)}$ is $\frac{1}{u}$ .
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(x + 1\right)$ :
    1. Differentiate $x + 1$ term by term:
      1. Apply the power rule: $x$ goes to $1$
      2. The derivative of the constant $1$ is zero.
      The result is: $1$
    The result of the chain rule is:
    
    $\frac{1}{x + 1}$
  The result of the chain rule is:
  
  $- \frac{1}{\left(x + 1\right) \log{\left(x + 1 \right)}^{2}}$
The result of the chain rule is:

$- \frac{3^{\frac{1}{\log{\left(x + 1 \right)}}} \log{\left(3 \right)}}{\left(x + 1\right) \log{\left(x + 1 \right)}^{2}}$
Now simplify:

$- \frac{3^{\frac{1}{\log{\left(x + 1 \right)}}} \log{\left(3 \right)}}{\left(x + 1\right) \log{\left(x + 1 \right)}^{2}}$

The answer is:

$- \frac{3^{\frac{1}{\log{\left(x + 1 \right)}}} \log{\left(3 \right)}}{\left(x + 1\right) \log{\left(x + 1 \right)}^{2}}$
