simplify cubit root ^3 radical 54

1 answer

To simplify the cube root of 54, we can start by factoring 54 into its prime factors:

\[ 54 = 2 \times 3^3 \]

Now, we can express \(\sqrt[3]{54}\) using its prime factors:

\[ \sqrt[3]{54} = \sqrt[3]{2 \times 3^3} \]

Using properties of cube roots, we can separate the factors:

\[ \sqrt[3]{54} = \sqrt[3]{2} \times \sqrt[3]{3^3} \]

Since \(\sqrt[3]{3^3} = 3\), we have:

\[ \sqrt[3]{54} = 3 \times \sqrt[3]{2} \]

Thus, the simplified form of the cube root of 54 is:

\[ \sqrt[3]{54} = 3\sqrt[3]{2} \]
