anonymous 5 years ago simplify ^3√27+3^3√16-4^3√54

$\sqrt[3]{27} = 3$$3*\sqrt[3]{16} = 6\sqrt[3]{2}$$4*\sqrt[3]{54} = 12\sqrt[3]{2}$$3 + 6\sqrt[3]{2}-12\sqrt[3]{2} = 3-6\sqrt[3]{2}$

you're asking similar questions so i think it might be better to slow down and try to figure out the mechanics of it first.
