n*4*x*\/ 2*x + 3

$$x 4 n \sqrt{2 x + 3}$$

((n*4)*x)*sqrt(2*x + 3)

Detail solution

Apply the product rule:

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

$f{\left(x \right)} = x 4 n$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
1. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Apply the power rule: $x$ goes to $1$
  So, the result is: $4 n$
$g{\left(x \right)} = \sqrt{2 x + 3}$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
1. Let $u = 2 x + 3$ .
2. Apply the power rule: $\sqrt{u}$ goes to $\frac{1}{2 \sqrt{u}}$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(2 x + 3\right)$ :
  1. Differentiate $2 x + 3$ term by term:
    1. The derivative of a constant times a function is the constant times the derivative of the function.
      1. Apply the power rule: $x$ goes to $1$
      So, the result is: $2$
    2. The derivative of the constant $3$ is zero.
    The result is: $2$
  The result of the chain rule is:
  
  $\frac{1}{\sqrt{2 x + 3}}$
The result is: $\frac{4 n x}{\sqrt{2 x + 3}} + 4 n \sqrt{2 x + 3}$
Now simplify:

$\frac{12 n \left(x + 1\right)}{\sqrt{2 x + 3}}$

The answer is:

$\frac{12 n \left(x + 1\right)}{\sqrt{2 x + 3}}$
