(D) આપેલ છે કે $I_{n+1} = \int_{0}^{1} \frac{x^{n+1} - 1}{x + 1} dx$.$I_{n+1} + I_n = \int_{0}^{1} \frac{x^{n+1} - 1}{x + 1} dx + \int_{0}^{1} \frac{x^n - 1}{x + 1} dx$ ધ્યાનમાં લો.$I_{n+1} + I_n = \int_{0}^{1} \frac{x^{n+1} + x^n - 2}{x + 1} dx$.$I_{n+1} + I_n = \int_{0}^{1} \frac{x^n(x + 1) - 2}{x + 1} dx$.$I_{n+1} + I_n = \int_{0}^{1} x^n dx - 2 \int_{0}^{1} \frac{1}{x + 1} dx$.$I_{n+1} + I_n = \left[ \frac{x^{n+1}}{n+1} \right]_0^1 - 2 [\log(x + 1)]_0^1$.$I_{n+1} + I_n = \frac{1}{n+1} - 2 \log 2$.$n = 10$ માટે,આપણને $I_{11} + I_{10} = \frac{1}{11} - 2 \log 2$ મળે છે.તેથી,$I_{10} + I_{11} + 2 \log 2 = \frac{1}{11}$.

જો $I_{n+1} = \int_{0}^{1} \frac{x^{n+1} - 1}{x + 1} dx$ હોય,તો $I_{10} + I_{11} + 2 \log 2$ ની કિંમત શું થાય?
