(C) ધારો કે $I = \int_0^{\frac{\pi}{2}} \frac{(\sec x)^{1/n}}{(\sec x)^{1/n} + (\operatorname{cosec} x)^{1/n}} dx \dots (i)$ ગુણધર્મ $\int_0^a f(x) dx = \int_0^a f(a-x) dx$ નો ઉપયોગ કરતા: $I = \int_0^{\frac{\pi}{2}} \frac{(\sec(\frac{\pi}{2}-x))^{1/n}}{(\sec(\frac{\pi}{2}-x))^{1/n} + (\operatorname{cosec}(\frac{\pi}{2}-x))^{1/n}} dx$ $I = \int_0^{\frac{\pi}{2}} \frac{(\operatorname{cosec} x)^{1/n}}{(\operatorname{cosec} x)^{1/n} + (\sec x)^{1/n}} dx \dots (ii)$ $(i)$ અને $(ii)$ નો સરવાળો કરતા: $2I = \int_0^{\frac{\pi}{2}} \frac{(\sec x)^{1/n} + (\operatorname{cosec} x)^{1/n}}{(\sec x)^{1/n} + (\operatorname{cosec} x)^{1/n}} dx$ $2I = \int_0^{\frac{\pi}{2}} 1 dx$ $2I = [x]_0^{\frac{\pi}{2}} = \frac{\pi}{2}$ $I = \frac{\pi}{4}$

$\int_0^{\frac{\pi}{2}} \left( \frac{\sqrt[n]{\sec x}}{\sqrt[n]{\sec x} + \sqrt[n]{\operatorname{cosec} x}} \right) dx = $
