Desenvolvendo o cálculo, temos:
![5\sqrt[3]{2}-8\sqrt[3]{3}+2-4\sqrt[3]{2}+8\sqrt[3]{2}\\\\
5\sqrt[3]{2}-4\sqrt[3]{2}+8\sqrt[3]{2}-8\sqrt[3]{3}+2\\\\
\sqrt[3]{2}(5-4+8)-8\sqrt[3]{3}+2\\\\
9\sqrt[3]{2}-8\sqrt[3]{3}+2](https://tex.z-dn.net/?f=5%5Csqrt%5B3%5D%7B2%7D-8%5Csqrt%5B3%5D%7B3%7D%2B2-4%5Csqrt%5B3%5D%7B2%7D%2B8%5Csqrt%5B3%5D%7B2%7D%5C%5C%5C%5C%0A5%5Csqrt%5B3%5D%7B2%7D-4%5Csqrt%5B3%5D%7B2%7D%2B8%5Csqrt%5B3%5D%7B2%7D-8%5Csqrt%5B3%5D%7B3%7D%2B2%5C%5C%5C%5C%0A%5Csqrt%5B3%5D%7B2%7D%285-4%2B8%29-8%5Csqrt%5B3%5D%7B3%7D%2B2%5C%5C%5C%5C%0A9%5Csqrt%5B3%5D%7B2%7D-8%5Csqrt%5B3%5D%7B3%7D%2B2 "5\sqrt[3]{2}-8\sqrt[3]{3}+2-4\sqrt[3]{2}+8\sqrt[3]{2}\\\\
