\[\left( \sqrt[3]{x} + \sqrt[3]{2} \right)\left( \sqrt[3]{x^{2}} - \sqrt[3]{2x} + \sqrt[3]{4} \right) =\]
\[= 8 - \sqrt{x}\]
\[\left( \sqrt[3]{x} \right)^{3} + \left( \sqrt[3]{2} \right)^{3} = 8 - \sqrt{x}\]
\[x + 2 = 8 - \sqrt{x}\]
\[x + \sqrt{x} + 2 - 8 = 0\]
\[x + \sqrt{x} - 6 = 0\]
\[t = \sqrt{x};\ \ \ \ \ \ t \geq 0\]
\[t^{2} + t - 6 = 0\]
\[t_{1} = 2;\ \ \ \ \ \ \]
\[t_{2} = - 3\ \ \ (не\ подходит)\]
\[\sqrt{x} = 2 \Longrightarrow x = 4.\]
\[Ответ:\ \ x = 4.\]
