(C) ધારો કે $I = \int_{6}^{16} \frac{\log _{e} x^{2}}{\log _{e} x^{2} + \log _{e}(x-22)^{2}} dx \dots(1)$ગુણધર્મ $\int_{a}^{b} f(x) dx = \int_{a}^{b} f(a+b-x) dx$ નો ઉપયોગ કરતા,જ્યાં $a+b = 6+16 = 22$:$I = \int_{6}^{16} \frac{\log _{e}(22-x)^{2}}{\log _{e}(22-x)^{2} + \log _{e}(22-(22-x))^{2}} dx$$I = \int_{6}^{16} \frac{\log _{e}(22-x)^{2}}{\log _{e}(22-x)^{2} + \log _{e} x^{2}} dx \dots(2)$$(1)$ અને $(2)$ નો સરવાળો કરતા:$2I = \int_{6}^{16} \frac{\log _{e} x^{2} + \log _{e}(22-x)^{2}}{\log _{e} x^{2} + \log _{e}(22-x)^{2}} dx$$2I = \int_{6}^{16} 1 dx = [x]_{6}^{16} = 16 - 6 = 10$$I = \frac{10}{2} = 5$

$\int \limits_{6}^{16} \frac{\log _{e} x^{2}}{\log _{e} x^{2}+\log _{e}\left(x^{2}-44 x+484\right)} d x$ ની કિંમત શોધો.
