Logarithm Simplification 46Ecfe
1. **State the problem:** Simplify the expression $$\frac{2 \log_x \sqrt{y} + \log_x y}{2 \log_{x^2} y}$$ where $x > 1$ and $y > 0$.
2. **Recall logarithm rules:**
- $\log_x a^m = m \log_x a$
- Change of base: $\log_{x^2} y = \frac{\log_x y}{\log_x x^2}$
- Since $\log_x x^2 = 2$, we have $\log_{x^2} y = \frac{\log_x y}{2}$
3. **Simplify numerator:**
- $\log_x \sqrt{y} = \log_x y^{1/2} = \frac{1}{2} \log_x y$
- So numerator: $2 \times \frac{1}{2} \log_x y + \log_x y = \log_x y + \log_x y = 2 \log_x y$
4. **Simplify denominator:**
- $2 \log_{x^2} y = 2 \times \frac{\log_x y}{2} = \log_x y$
5. **Combine numerator and denominator:**
$$\frac{2 \log_x y}{\log_x y} = 2$$
**Final answer:** $2$
