Hints:
- $lim_{xto +infty}e^{-x}sinfrac{2}{x} = 0$
- $lim_{xto +infty} frac{sin left(e^{-x}sinfrac{2}{x} right)}{e^{-x}sinfrac{2}{x}} = 1$
$endgroup$
$begingroup$
$lim_{xto+infty}xe^xsinleft(e^{-x}sinfrac{2}{x}right)$ is not to equal for the second $cdot$

Just use the hints and write: $$xe^xsinleft(e^{-x}sinfrac{2}{x}right) = xe^x cdot e^{-x}sinfrac{2}{x} cdot frac{sin left(e^{-x}sinfrac{2}{x} right)}{e^{-x}sinfrac{2}{x}} = 2cdot frac{sinfrac{2}{x}}{frac{2}{x}} cdot frac{sin left(e^{-x}sinfrac{2}{x} right)}{e^{-x}sinfrac{2}{x}}$$
