  _________
\/ 1 + 2*x

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

sqrt(1 + 2*x)

Detail solution

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

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

The answer is:

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