1. **State the problem:** Solve the equation $$4^{x-2} = \frac{1}{8}$$ for $x$.
2. **Recall the bases:** Note that $4$ and $8$ can be expressed as powers of $2$:
$$4 = 2^2 \quad \text{and} \quad 8 = 2^3$$
3. **Rewrite the equation using base 2:**
$$4^{x-2} = (2^2)^{x-2} = 2^{2(x-2)}$$
$$\frac{1}{8} = 8^{-1} = (2^3)^{-1} = 2^{-3}$$
4. **Set the exponents equal:** Since the bases are the same and nonzero, we can equate the exponents:
$$2(x-2) = -3$$
5. **Solve for $x$:**
$$2x - 4 = -3$$
$$2x = 1$$
$$x = \frac{1}{2}$$
**Final answer:** $$x = \frac{1}{2}$$
