Solve y=72x^3+14^9

$$y = 72 x ^ { 3 } + 14 ^ { 9 }$$

Solve for y

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

Solution Steps

Calculate 14 to the power of 9 and get 20661046784.

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

Solve for x (complex solution)

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

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

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

Solve for x

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