Transform

Detail solution

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

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

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

The answer is:

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