Answer 1

To find the cubic root of 189, we can simplify it:

1. First, let's factor 189:

   • \(189 = 3^3 \times 7\)

2. The cubic root of a product can be distributed as follows: \(\sqrt[3]{189} = \sqrt[3]{3^3 \times 7} = \sqrt[3]{3^3} \times \sqrt[3]{7} = 3 \cdot \sqrt[3]{7}\)

Thus, the cubic root of 189 is:

\[ 3 \sqrt[3]{7} \]

Looking at your options, the correct response is:

\(3 \sqrt[3]{7}\).
