Question

\(\left(\sqrt[3]{3}+\sqrt[3]{2}\right)^3\)

Answer 1

\(=\left(\sqrt[3]{3}\right)^3+3\cdot\sqrt[3]{3^2}\cdot\sqrt[3]{2}+3\cdot\sqrt[3]{3\cdot2^2}+2\)

\(=5+3\cdot\sqrt[3]{18}+3\sqrt[3]{12}\)

Answer 3

\(\left(\sqrt[3]{3}+\sqrt[3]{2}\right)^3=\left(\sqrt[3]{3}\right)^3+3\left(\sqrt[3]{3}\right)^2\sqrt[3]{2}+3\sqrt[3]{3}\left(\sqrt[3]{2}\right)^2+\left(\sqrt[3]{2}\right)^3\)

\(=3+3\sqrt[3]{18}+3\sqrt[3]{12}+2=5+3\sqrt[3]{18}+3\sqrt[3]{12}\)

Answer 4

\(\left(\sqrt[3]{3}+\sqrt[3]{2}\right)^3\)

\(=5+3\sqrt[3]{4}\sqrt[3]{3}+3\sqrt[3]{2}\sqrt[3]{9}\)

\(=5+3\sqrt[3]{12}+3\sqrt[3]{2}\sqrt[3]{9}\)

\(=5+3\sqrt[3]{12}+3\sqrt[3]{18}\)
