Step 2.2.3.1.1

Raising $0$ to any positive power yields $0$ .

$y = \frac{0}{\sqrt[3]{0 - 1}}$

Step 2.2.3.1.2

Subtract $1$ from $0$ .

$y = \frac{0}{\sqrt[3]{- 1}}$

Step 2.2.3.1.3

Rewrite $- 1$ as ${(- 1)}^{3}$ .

$y = \frac{0}{\sqrt[3]{{(- 1)}^{3}}}$

Step 2.2.3.1.4

Pull terms out from under the radical, assuming real numbers.

$y = \frac{0}{- 1}$

Step 2.2.3.2

Divide $0$ by $- 1$ .

$y = 0$

Step 2.3
