Question:

$\int\left(x^x\right)^x\left(2 x \log _e x+x\right) d x$ is equal to

Options:

$x^{\left(x^x\right)}+C$

$\left(x^x\right)^x+C$

$x^x . \log _e x+C$

none of these

Correct Answer:

none of these

Explanation:

Let

$I=\int\left(x^x\right)^x\left(2 x \log _e x+x\right) d x=\int x^{x^2}\left(2 x \log _e x+x\right) d x$

$\Rightarrow I=\int 1 \cdot d\left(x^{x^2}\right)=x^{x^2}+C=\left(x^x\right)^x+C$
