  /  3     
\/  x  - 1

$$\sqrt{x^{3} - 1}$$

sqrt(x^3 - 1)

Detail solution

Let $u = x^{3} - 1$ .
Apply the power rule: $\sqrt{u}$ goes to $\frac{1}{2 \sqrt{u}}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(x^{3} - 1\right)$ :
1. Differentiate $x^{3} - 1$ term by term:
  1. Apply the power rule: $x^{3}$ goes to $3 x^{2}$
  2. The derivative of the constant $-1$ is zero.
  The result is: $3 x^{2}$
The result of the chain rule is:

$\frac{3 x^{2}}{2 \sqrt{x^{3} - 1}}$
Now simplify:

$\frac{3 x^{2}}{2 \sqrt{x^{3} - 1}}$

The answer is:

$\frac{3 x^{2}}{2 \sqrt{x^{3} - 1}}$
