$$y=72x^{3}[phone]$$

Løs for x (complex solution)

$$x=\frac{e^{\frac{2\pi i}{3}}\sqrt[3]{3\left(y-20661046784\right)}}{6}$$

$$x=\frac{\sqrt[3]{3\left(y-20661046784\right)}}{6}$$

$$x=\frac{e^{\frac{4\pi i}{3}}\sqrt[3]{3\left(y-20661046784\right)}}{6}$$

Løs for x

$$x=\frac{\sqrt[3]{3\left(y-20661046784\right)}}{6}$$
