1. **State the problem:** Simplify the expression $$\frac{\left(\frac{1}{2}\right)^x \cdot 8^x}{4^x}$$.
2. **Recall the laws of exponents:**
- When multiplying with the same exponent, multiply the bases: $$a^x \cdot b^x = (a \cdot b)^x$$.
- When dividing with the same exponent, divide the bases: $$\frac{a^x}{b^x} = \left(\frac{a}{b}\right)^x$$.
3. **Rewrite the bases as powers of 2:**
- $$\frac{1}{2} = 2^{-1}$$
- $$8 = 2^3$$
- $$4 = 2^2$$
4. **Substitute these into the expression:**
$$\frac{(2^{-1})^x \cdot (2^3)^x}{(2^2)^x}$$
5. **Apply the power of a power rule:**
$$\frac{2^{-x} \cdot 2^{3x}}{2^{2x}}$$
6. **Multiply the numerator terms:**
$$2^{-x + 3x} = 2^{2x}$$
7. **Divide numerator by denominator:**
$$\frac{2^{2x}}{2^{2x}} = 2^{2x - 2x} = 2^0 = 1$$
**Final answer:** $$1$$
