  _________
\/ 4*x + 1

$$\sqrt{4 x + 1}$$

sqrt(4*x + 1)

Detail solution

Let $u = 4 x + 1$ .
Apply the power rule: $\sqrt{u}$ goes to $\frac{1}{2 \sqrt{u}}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(4 x + 1\right)$ :
1. Differentiate $4 x + 1$ 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: $4$
  2. The derivative of the constant $1$ is zero.
  The result is: $4$
The result of the chain rule is:

$\frac{2}{\sqrt{4 x + 1}}$
Now simplify:

$\frac{2}{\sqrt{4 x + 1}}$

The answer is:

$\frac{2}{\sqrt{4 x + 1}}$
