Logarithm Equation Af137A
1. **State the problem:** Solve the equation $$\ln(x - 8) + \ln 3 = 3$$ given the square root values 4 and 25 (which might be hints for simplification).
2. **Recall the logarithm property:** The sum of logarithms with the same base can be combined as the logarithm of the product:
$$\ln a + \ln b = \ln(ab)$$
3. **Apply the property:**
$$\ln(x - 8) + \ln 3 = \ln(3(x - 8))$$
So the equation becomes:
$$\ln(3(x - 8)) = 3$$
4. **Rewrite the equation in exponential form:**
Since $$\ln y = 3$$ means $$y = e^3$$, we have:
$$3(x - 8) = e^3$$
5. **Solve for $$x$$:**
$$x - 8 = \frac{e^3}{3}$$
$$x = 8 + \frac{e^3}{3}$$
6. **Check domain restrictions:**
The argument of the logarithm must be positive:
$$x - 8 > 0 \implies x > 8$$
Our solution satisfies this.
7. **Final answer:**
$$\boxed{x = 8 + \frac{e^3}{3}}$$
