Answer 1

Do you know what the radical sign does?

Answer 2

yes i think you have to get the square root

Answer 3

ah you don't have to worry about the numbers for this problem, because,

\[\sqrt[a]{n} = n ^{\frac{ 1 }{ a }}\]
\[(n ^{a})^{b} = n ^{a*b}\]

so as an example
\[(\sqrt[3]{7.33} )^{3} = (7.33^{\frac{ 1 }{ 3 }})^{3} = 7.33^{\frac{ 1 }{ 3 }*3} = 7.33^{1} = 7.33\]
