### Simplifying Radical Expressions: An Example

**Question**: Which expression is equivalent to \(\sqrt[5]{6x^3y^6}\)?

**Options**:
1. \(6^5x^{15}y^{18}\)
2. \(6x^{\frac{3}{5}}y^{\frac{6}{5}}\)
3. \(6^{\frac{1}{5}}x^{3}y^{6}\)
4. \(6^{\frac{1}{5}}x^{\frac{3}{5}}y^{\frac{6}{5}}\)

**Explanation**:
To find an equivalent expression for the fifth root of the given expression, we can break down the problem step by step.

The given expression is \(\sqrt[5]{6x^3y^6}\).

Recall that the \(n\)-th root of a product can be written as the product of the \(n\)-th roots:

\[
\sqrt[5]{6x^3y^6} = 6^{\frac{1}{5}} (x^3)^{\frac{1}{5}} (y^6)^{\frac{1}{5}}
\]

Next, simplify each part individually:

1. \(6^{\frac{1}{5}}\)
2. \((x^3)^{\frac{1}{5}} = x^{\frac{3}{5}}\)
3. \((y^6)^{\frac{1}{5}} = y^{\frac{6}{5}}\)

Combining these, we get:

\[
6^{\frac{1}{5}} x^{\frac{3}{5}} y^{\frac{6}{5}}
\]

Thus, the equivalent expression is:

\[
6^{\frac{1}{5}} x^{\frac{3}{5}} y^{\frac{6}{5}}
\]

**Correct Option**:
The correct answer is the last option:
\[ 
\boxed{6^{\frac{1}{5}} x^{\frac{3}{5}} y^{\frac{6}{5}}}
\]
