1. **Problem:** Simplify the expression $$\sqrt[3]{8x^7}$$.
2. **Recall the rules:**
- The cube root of a number is the same as raising it to the power of $\frac{1}{3}$.
- The square root of a number is the same as raising it to the power of $\frac{1}{2}$.
- When raising a power to another power, multiply the exponents: $$(a^m)^n = a^{m \cdot n}$$.
3. **Step-by-step simplification:**
$$\sqrt[3]{8x^7} = (8x^7)^{\frac{1}{3}}$$
4. If the problem involves taking the square root of the cube root, then:
$$\sqrt{\sqrt[3]{8x^7}} = \left((8x^7)^{\frac{1}{3}}\right)^{\frac{1}{2}}$$
5. Multiply the exponents:
$$= (8x^7)^{\frac{1}{3} \cdot \frac{1}{2}} = (8x^7)^{\frac{1}{6}}$$
6. Apply the exponent to each factor:
$$= 8^{\frac{1}{6}} \cdot x^{7 \cdot \frac{1}{6}} = 8^{\frac{1}{6}} x^{\frac{7}{6}}$$
7. Simplify $8^{\frac{1}{6}}$:
Since $8 = 2^3$,
$$8^{\frac{1}{6}} = (2^3)^{\frac{1}{6}} = 2^{\frac{3}{6}} = 2^{\frac{1}{2}} = \sqrt{2}$$
8. **Final simplified expression:**
$$\sqrt{2} \cdot x^{\frac{7}{6}}$$
This is the simplified form of the original expression.
