Answer & Solution

Correct Answer

(A) 1

Step-by-step Solution

Detailed explanation

Given \(\int \frac{\mathrm{dx}}{\mathrm{x}^{2022}\left(1+\mathrm{x}^{2022}\right)^{1 / 2002}}\) \[ \Rightarrow \int \frac{\mathrm{dx}}{\mathrm{x}^{2023}\left(1+\mathrm{x}^{-2022}\right)^{1 / 2022}} \] Let \(1+\mathrm{x}^{-2022}=\mathrm{t}\)…
