$\left[ \int_{0}^{2} \sqrt{x + \sqrt{x + \sqrt{x + \dots \infty}}} \, dx \right]$ ની કિંમત શોધો (જ્યાં $[\cdot]$ એ $G.I.F.$ છે)

ધારો કે $f(x) + 2f\left(\frac{1}{x}\right) = x^2 + 5$ અને $2g(x) - 3g\left(\frac{1}{x}\right) = x$ જ્યાં $x > 0$. જો $\alpha = \int_1^2 f(x) dx$ અને $\beta = \int_1^2 g(x) dx$ હોય,તો $9\alpha + \beta$ ની કિંમત શોધો:

જો $\int\limits_0^a {\frac{{dx}}{{\sqrt {x + a} + \sqrt x }}} = \int\limits_0^{\frac{\pi }{8}} {\frac{{2\tan \theta }}{{\sin 2\theta }}} d\theta$ હોય,તો $a$ ની કિંમત $(a > 0)$ શોધો.
