Answer 2

✍✍HERE IS YOUR SOLUTION…⬇⬇
======================================
$2 \times 1 + \frac{1}{ \sqrt{2} } - \frac{1}{ \sqrt{2} } \\ \\ = 2 \times 1 \\ \\ = 2$

Or ,

$2\times 1 + \frac{1}{ \sqrt{2} } - \frac{1}{ \sqrt{2} } \\ \\ = 2+\frac{1}{ \sqrt{2} } - \frac{1}{ \sqrt{2} } \\ \\ =\frac{2 \sqrt{2}+1-1}{\sqrt{2}} \\ \\ = \frac{2\sqrt{2}}{\sqrt{2}} \\ \\ = 2$
