Selesaikan untuk x (complex solution)
x=-\frac{9^{\frac{2}{3}}\left(1+\sqrt{3}i\right)\left(-\sqrt[3]{9\left(2\sqrt{83}+15\sqrt{3}\right)}i-\sqrt[3]{2\sqrt{249}+45}+2\sqrt[3]{45-2\sqrt{249}}\right)}{72}\approx -0.796096793+0.38898626i
x = \frac{9 ^ {\frac{2}{3}} {(\sqrt[3]{2 \sqrt{249} + 45} + \sqrt[3]{45 - 2 \sqrt{249}})}}{18} \approx 1.592193586
