Answer 1

To find the cubic root of 96, we can express 96 as \( 2^5 \times 3^1 \).

Now we calculate the cubic root:

\[
\sqrt[3]{96} = \sqrt[3]{2^5 \times 3^1} = \sqrt[3]{2^5} \times \sqrt[3]{3^1}
\]

Breaking this down further:

\[
\sqrt[3]{2^5} = 2^{5/3} = 2^{1 + 2/3} = 2 \cdot 2^{2/3} = 2 \cdot \sqrt[3]{4}
\]

And

\[
\sqrt[3]{3^1} = 3^{1/3}
\]

Putting it all together:

\[
\sqrt[3]{96} = 2 \cdot \sqrt[3]{4} \cdot \sqrt[3]{3} = 2 \cdot \sqrt[3]{12}
\]

So the cubic root of 96 is \( 2 \sqrt[3]{12} \).

Among the given responses, the one that matches this result is:

\( 2 \sqrt[3]{12} \)
