Solve Exponent Equation F3825F
1. **State the problem:** Solve the equation $$2\left(\frac{1}{8}\right) = 32^{n-1}$$ for $n$.
2. **Rewrite the equation:** Simplify the left side:
$$2 \times \frac{1}{8} = \frac{2}{8} = \frac{1}{4}$$
So the equation becomes:
$$\frac{1}{4} = 32^{n-1}$$
3. **Express bases as powers of 2:**
Note that:
$$\frac{1}{4} = 4^{-1} = (2^2)^{-1} = 2^{-2}$$
and
$$32 = 2^5$$
So:
$$32^{n-1} = (2^5)^{n-1} = 2^{5(n-1)}$$
4. **Set the exponents equal:**
Since the bases are the same (base 2), the exponents must be equal:
$$-2 = 5(n-1)$$
5. **Solve for $n$:**
$$-2 = 5n - 5$$
Add 5 to both sides:
$$-2 + 5 = 5n$$
$$3 = 5n$$
Divide both sides by 5:
$$n = \frac{3}{5}$$
**Final answer:**
$$n = \frac{3}{5}$$
