1. **State the problem:** Solve the equation $$\log \sqrt{3x + 1} = 1 + \log \sqrt{2x - 3}$$ for $x$.
2. **Recall logarithm properties:**
- $\log a^b = b \log a$
- $\log a - \log b = \log \frac{a}{b}$
- $\log 10 = 1$ (assuming base 10 logarithm)
3. **Rewrite the equation:**
$$\log \sqrt{3x + 1} = 1 + \log \sqrt{2x - 3}$$
can be written as
$$\log (3x + 1)^{\frac{1}{2}} = \log 10 + \log (2x - 3)^{\frac{1}{2}}$$
4. **Use log addition rule:**
$$\log (3x + 1)^{\frac{1}{2}} = \log \left(10 \times (2x - 3)^{\frac{1}{2}}\right)$$
5. **Since $\log A = \log B$, then $A = B$: **
$$ (3x + 1)^{\frac{1}{2}} = 10 (2x - 3)^{\frac{1}{2}} $$
6. **Square both sides to eliminate square roots:**
$$ 3x + 1 = 100 (2x - 3) $$
7. **Expand and simplify:**
$$ 3x + 1 = 200x - 300 $$
8. **Bring all terms to one side:**
$$ 3x + 1 - 200x + 300 = 0 $$
$$ -197x + 301 = 0 $$
9. **Solve for $x$:**
$$ -197x = -301 $$
$$ x = \frac{301}{197} $$
10. **Check domain restrictions:**
- Inside the logarithms, arguments must be positive:
$$ 3x + 1 > 0 \Rightarrow x > -\frac{1}{3} $$
$$ 2x - 3 > 0 \Rightarrow x > \frac{3}{2} $$
Since $x = \frac{301}{197} \approx 1.527 > 1.5$, it satisfies the domain.
**Final answer:**
$$ x = \frac{301}{197} $$
