求解 x, y, z 的值
x = \frac{4 \cdot 45 ^ {\frac{2}{3}} {(18 \sqrt[3]{2} {(-\sqrt[3]{\sqrt{6600415449} + 81243} - \sqrt[3]{81243 - \sqrt{6600415449}})} + 15 \sqrt[3]{2} \sqrt[3]{\sqrt{6600415449} + 81243} + 15 \sqrt[3]{2} \sqrt[3]{81243 - \sqrt{6600415449}} + 14958 \sqrt[3]{45})}}{3645} \approx 735.782661144
y=\frac{2\times 45^{\frac{2}{3}}\left(9\left(10\sqrt[3]{2}\left(\sqrt[3]{\sqrt{6600415449}+81243}+\sqrt[3]{81243-\sqrt{6600415449}}\right)-4443\sqrt[3]{45}\right)-60\sqrt[3]{2}\sqrt[3]{\sqrt{6600415449}+81243}-60\sqrt[3]{2}\sqrt[3]{81243-\sqrt{6600415449}}\right)}{3645}\approx -972.913305722
z = -\frac{\sqrt[3]{2} \cdot 45 ^ {\frac{2}{3}} {(\sqrt[3]{\sqrt{6600415449} + 81243} + \sqrt[3]{81243 - \sqrt{6600415449}})}}{135} \approx -6.489012425
