1. **State the problem:** Solve the equation $$(x - 3)^{\frac{3}{5}} = 8$$ for $x$.
2. **Isolate the expression:** The equation is already isolated with the power expression on one side.
3. **Eliminate the fractional exponent:** To remove the fractional exponent $\frac{3}{5}$, raise both sides of the equation to the reciprocal power $\frac{5}{3}$:
$$\left((x - 3)^{\frac{3}{5}}\right)^{\frac{5}{3}} = 8^{\frac{5}{3}}$$
4. **Simplify the left side:** Using the property $(a^m)^n = a^{mn}$,
$$ (x - 3)^{\frac{3}{5} \times \frac{5}{3}} = (x - 3)^1 = x - 3 $$
5. **Calculate the right side:**
$$ 8^{\frac{5}{3}} = \left(8^{\frac{1}{3}}\right)^5 $$
Since $8^{\frac{1}{3}} = 2$ (cube root of 8),
$$ 2^5 = 32 $$
6. **Set the simplified equation:**
$$ x - 3 = 32 $$
7. **Solve for $x$:**
$$ x = 32 + 3 = 35 $$
**Final answer:** $x = 35$
