1. **State the problem:** Solve the equation $$6^x = \frac{12^x}{8}$$ for $x$.
2. **Rewrite the equation:** Multiply both sides by 8 to eliminate the denominator:
$$8 \cdot 6^x = 12^x$$
3. **Express bases as powers of 2 and 3:**
$$6 = 2 \times 3$$
$$12 = 2^2 \times 3$$
So,
$$8 \cdot (2 \times 3)^x = (2^2 \times 3)^x$$
4. **Rewrite the equation using exponents:**
$$8 \cdot 2^x \cdot 3^x = 2^{2x} \cdot 3^x$$
5. **Express 8 as a power of 2:**
$$8 = 2^3$$
So,
$$2^3 \cdot 2^x \cdot 3^x = 2^{2x} \cdot 3^x$$
6. **Combine powers of 2 on the left:**
$$2^{3+x} \cdot 3^x = 2^{2x} \cdot 3^x$$
7. **Divide both sides by $3^x$ to cancel:**
$$\frac{2^{3+x} \cdot \cancel{3^x}}{\cancel{3^x}} = \frac{2^{2x} \cdot \cancel{3^x}}{\cancel{3^x}}$$
Which simplifies to:
$$2^{3+x} = 2^{2x}$$
8. **Since the bases are equal, set exponents equal:**
$$3 + x = 2x$$
9. **Solve for $x$:**
$$3 = 2x - x$$
$$3 = x$$
**Final answer:**
$$x = 3$$
