\/ 2 *x

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

1/(sqrt(2)*x^2)

Detail solution

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

$- \frac{\sqrt{2}}{x^{3}}$

The answer is:

$- \frac{\sqrt{2}}{x^{3}}$
