Answer & Solution

Correct Answer

(D) \(\frac{16}{5}\)

Step-by-step Solution

Detailed explanation

\begin{aligned} & \text { } I=\int_0^1 \frac{x}{(1-x)^{3 / 4}} d x, x=\sin ^2 \theta \Rightarrow d x=2 \sin \theta \cos \theta d \theta \\ & \because I=\int_0^{\pi / 2} \frac{\sin ^2 \theta}{\cos ^{3 / 2} \theta} \times 2 \sin \theta \cos \theta d \theta \\ & =2 \times…
