To rewrite \(\sqrt[3]{189}\) as the product of an integer and another irrational cube root, we can start by factoring \(189\).
First, we find the prime factorization of \(189\):
\[
189 = 3^3 \times 7
\]
Now, we can express \(\sqrt[3]{189}\) using this factorization:
\[
\sqrt[3]{189} = \sqrt[3]{3^3 \times 7}
\]
We can separate the cube root:
\[
\sqrt[3]{189} = \sqrt[3]{3^3} \times \sqrt[3]{7}
\]
Since \(\sqrt[3]{3^3} = 3\), we have:
\[
\sqrt[3]{189} = 3 \times \sqrt[3]{7}
\]
Thus, \(\sqrt[3]{189}\) can be rewritten as:
\[
\sqrt[3]{189} = 3\sqrt[3]{7}
\]
This is the final result.

Sure! Let's rewrite \(\sqrt[3]{189}\) as the product of an integer and another irrational cube root.
1. **Factor \(189\)**:
\[
189 = 3^3 \times 7
\]
2. **Write the cube root**:
\[
\sqrt[3]{189} = \sqrt[3]{3^3 \times 7}
\]
3. **Separate the cube roots**:
\[
\sqrt[3]{189} = \sqrt[3]{3^3} \times \sqrt[3]{7}
\]
4. **Simplify**:
\[
\sqrt[3]{3^3} = 3
\]
Thus,
\[
\sqrt[3]{189} = 3 \times \sqrt[3]{7}
\]
So, the final expression is:
\[
\sqrt[3]{189} = 3\sqrt[3]{7}
