Differentiate Log E91C5D
1. **State the problem:** Differentiate the function $$y = 2x \log_3(\sqrt{x})$$.
2. **Recall the formula and rules:**
- The derivative of a product $$uv$$ is $$u'v + uv'$$.
- Change of base formula for logarithms: $$\log_a b = \frac{\ln b}{\ln a}$$.
- Derivative of $$\ln x$$ is $$\frac{1}{x}$$.
- Derivative of $$x^n$$ is $$nx^{n-1}$$.
3. **Rewrite the function:**
$$y = 2x \log_3(x^{1/2}) = 2x \cdot \frac{\ln(x^{1/2})}{\ln 3} = 2x \cdot \frac{1}{2} \frac{\ln x}{\ln 3} = \frac{2x}{2} \cdot \frac{\ln x}{\ln 3} = \frac{x \ln x}{\ln 3}$$
4. **Differentiate using product rule:**
Let $$u = x$$ and $$v = \frac{\ln x}{\ln 3}$$.
$$u' = 1$$
$$v' = \frac{1}{x \ln 3}$$
Then,
$$y' = u'v + uv' = 1 \cdot \frac{\ln x}{\ln 3} + x \cdot \frac{1}{x \ln 3} = \frac{\ln x}{\ln 3} + \frac{1}{\ln 3}$$
5. **Final answer:**
$$y' = \frac{\ln x + 1}{\ln 3}$$
