$$\sqrt{\frac{y - 2}{2}}$$

sqrt((y - 2)/2)

Detail solution

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

$\frac{\sqrt{2}}{4 \sqrt{y - 2}}$
Now simplify:

$\frac{\sqrt{2}}{4 \sqrt{y - 2}}$

The answer is:

$\frac{\sqrt{2}}{4 \sqrt{y - 2}}$
