Answers: 2
![\sqrt[3]{216\times27}\\\\\text{Use:}\ \sqrt[n]{a\cdot b}=\sqrt[n]a\cdot\sqrt[n]b\\\\\sqrt[3]{216\times27}=\sqrt[3]{216}\cdot\sqrt[3]{27}=6\cdot3=18\\\\.........................................................\\\\\sqrt[3]{216}=6\ \text{because}\ 6^3=216\\\\\sqrt[3]{27}=3\ \text{because}\ 3^3=27](/tpl/images/0090/4485/56cea.png)
