Selesaikan y=72x^3+14^9

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

Cari nilai y

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

Langkah Solusi

Hitung 14 sampai pangkat 9 dan dapatkan 20661046784.

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

Cari nilai x (complex solution)

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

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

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

Cari nilai x

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