Answer & Solution

Correct Answer

(A) \(\frac{1}{3}\left[x^3 \psi\left(x^3\right)\right]-\int x^2 \psi\left(x^3\right) d x\)

Step-by-step Solution

Detailed explanation

\(\int f(\mathrm{x}) \mathrm{dx}=\psi(\mathrm{x})\) Let \(\mathrm{I}=\int x^5 f\left(x^3\right) d x=\int x^3 f\left(x^3\right) x^2 d x\) Let \(x^3=t \Rightarrow 3 x^2 d x=d t \Rightarrow x^2 d x=\frac{d t}{3}\)…
