Verified Solution

Answer & Solution

Correct Answer

(A) \(0\)

Step-by-step Solution

Detailed explanation

\(I=\int_0^{\infty}\left(x^{12}+x^{-12}\right) \frac{\log x}{x} d x\) Put \(t=\frac{1}{x} \Rightarrow d t=-\frac{1}{x^2} d x\) \(\Rightarrow \quad-x d t=\frac{1}{x} d x \Rightarrow-\frac{d t}{t}=\frac{1}{x} d x\)…
