1. **Problema:** Resolver la ecuación $2 \log x - 3 + \log \left(\frac{x}{10}\right) = 0$.
2. **Fórmulas y reglas importantes:**
- Propiedad de logaritmos: $a \log b = \log b^a$.
- Suma de logaritmos: $\log a + \log b = \log (ab)$.
- Para resolver, se debe simplificar y despejar $x$.
3. **Desarrollo:**
\begin{align*}
&2 \log x - 3 + \log \left(\frac{x}{10}\right) = 0 \\
&\Rightarrow \log x^2 - 3 + \log \left(\frac{x}{10}\right) = 0 \\
&\Rightarrow \log x^2 + \log \left(\frac{x}{10}\right) - 3 = 0 \\
&\Rightarrow \log \left(x^2 \cdot \frac{x}{10}\right) - 3 = 0 \\
&\Rightarrow \log \left(\frac{x^3}{10}\right) - 3 = 0 \\
&\Rightarrow \log \left(\frac{x^3}{10}\right) = 3 \\
&\Rightarrow \frac{x^3}{10} = 10^3 \quad \text{(porque } \log a = b \Rightarrow a = 10^b\text{)} \\
&\Rightarrow \frac{x^3}{10} = 1000 \\
&\Rightarrow x^3 = 1000 \times 10 = 10000 \\
&\Rightarrow x = \sqrt[3]{10000} \\
&\Rightarrow x = 10 \sqrt[3]{10}
\end{align*}
4. **Respuesta final:**
$$x = 10 \sqrt[3]{10}$$
