Answer 2

$\bold{\large{\red{\tt{ANSWER}}}}$

$\frac{2}{5} \sqrt{50} - \sqrt{162} + \sqrt{98}$

$- > \frac{2}{5} \sqrt{25 \times 2} - \sqrt{81 \times 2} + \sqrt{49 \times 2}$

$- > \frac{2}{5} \times 5 \sqrt{2} - 9 \sqrt{2} + 7 \sqrt{2}$

$- > 2 \sqrt{2} - 9 \sqrt{2} + 7 \sqrt{2}$

$- > - 7 \sqrt{2} + 7 \sqrt{2}$

$- > 0$
