(\sqrt[3]{36}-\sqrt[3]{4})\cdot \sqrt[3]{6}=\sqrt[3]{36\cdot 6}-\sqrt[3]{4\cdot 6}=\sqrt[3]{6^2\cdot 6}-\sqrt[3]{2^2\cdot 2\cdot 3}=\\\\=\sqrt[3]{6^3}-\sqrt[3]{2^3\cdot 3}=6-2\sqrt[3]{3}

( \sqrt[3]{36} - \sqrt[3]{4} ) \times \sqrt[3]{6}
Раскрываем скобки
 \sqrt[3]{36} \times \sqrt[3]{6} \: - \sqrt[3]{4} \times \sqrt[3]{6} = \sqrt[3]{216} - \sqrt[3]{24}
Вычесляем кубический корень
6 - \sqrt[3]{24} = 6 - \sqrt[3]{3 \times {2}^{3} } = 6 - 2 \sqrt[3]{3}
