1. **State the problem:** Simplify the expression $$\sqrt[3]{\frac{18}{125}}$$.
2. **Recall the cube root property:** The cube root of a fraction is the fraction of the cube roots, i.e., $$\sqrt[3]{\frac{a}{b}} = \frac{\sqrt[3]{a}}{\sqrt[3]{b}}$$.
3. **Apply the property:**
$$\sqrt[3]{\frac{18}{125}} = \frac{\sqrt[3]{18}}{\sqrt[3]{125}}$$
4. **Simplify the denominator:** Since $$125 = 5^3$$, we have
$$\sqrt[3]{125} = 5$$
5. **Simplify the numerator:** Factor 18 as $$18 = 9 \times 2 = 3^2 \times 2$$. Since 3 is not a perfect cube, we keep it inside the root:
$$\sqrt[3]{18} = \sqrt[3]{3^2 \times 2} = \sqrt[3]{3^2} \times \sqrt[3]{2}$$
6. **Write the simplified expression:**
$$\frac{\sqrt[3]{18}}{\sqrt[3]{125}} = \frac{\sqrt[3]{3^2 \times 2}}{5} = \frac{\sqrt[3]{18}}{5}$$
7. **Final answer:**
$$\boxed{\frac{\sqrt[3]{18}}{5}}$$
This is the simplest exact form since 18 is not a perfect cube and cannot be simplified further under the cube root.
