To find the cubic root of 96, we write this as:

\[ \sqrt[3]{96} \]

To simplify \( \sqrt[3]{96} \), we can factor 96 into its prime factors:

\[ 96 = 2^5 \times 3^1 \]

Now we can apply the cube root to these factors:

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

Next, we simplify each term:

  1. \(\sqrt[3]{2^5} = 2^{5/3} = 2^{1 + 2/3} = 2 \times 2^{2/3}\), which can be written as \(2 \sqrt[3]{4}\).
  2. \(\sqrt[3]{3^1} = 3^{1/3} = \sqrt[3]{3}\).

Combining these, we get:

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

Thus, the cubic root of 96 can be expressed as:

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

Out of the given responses, the closest match is:

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

This is the answer.
