(D) ધારો કે $I = \int_{2}^{4} \frac{\log(x^2)}{\log(x^2) + \log((6-x)^2)} \, dx$. ગુણધર્મ $\log(a^2) = 2\log|a|$ નો ઉપયોગ કરતા: $I = \int_{2}^{4} \frac{2\log x}{2\log x + 2\log(6-x)} \, dx = \int_{2}^{4} \frac{\log x}{\log x + \log(6-x)} \, dx \quad \dots(1)$. ગુણધર્મ $\int_{a}^{b} f(x) \, dx = \int_{a}^{b} f(a+b-x) \, dx$ નો ઉપયોગ કરતા,જ્યાં $a+b = 2+4 = 6$: $I = \int_{2}^{4} \frac{\log(6-x)}{\log(6-x) + \log(6-(6-x))} \, dx = \int_{2}^{4} \frac{\log(6-x)}{\log(6-x) + \log x} \, dx \quad \dots(2)$. $(1)$ અને $(2)$ નો સરવાળો કરતા: $2I = \int_{2}^{4} \frac{\log x + \log(6-x)}{\log x + \log(6-x)} \, dx = \int_{2}^{4} 1 \, dx$. $2I = [x]_{2}^{4} = 4 - 2 = 2$. $I = 1$.

$\int_{2}^{4} \frac{\log(x^2)}{\log(x^2) + \log(36 - 12x + x^2)} \, dx = $
