$$\sqrt{\frac{5 - x}{2}}$$

sqrt((5 - x)/2)

Detail solution

Let $u = \frac{5 - x}{2}$ .
Apply the power rule: $\sqrt{u}$ goes to $\frac{1}{2 \sqrt{u}}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \frac{5 - x}{2}$ :
1. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Differentiate $5 - x$ term by term:
    1. The derivative of the constant $5$ 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: $-1$
    The result is: $-1$
  So, the result is: $- \frac{1}{2}$
The result of the chain rule is:

$- \frac{\sqrt{2}}{4 \sqrt{5 - x}}$

The answer is:

$- \frac{\sqrt{2}}{4 \sqrt{5 - x}}$
