Answer 1

Answer:

3-2√2

Step-by-step explanation:

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

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

$\frac{ {( \sqrt{2} - 1)}^{2} }{2 - 1}$

(a+b)(a-b) = a2-b2

$2 + 1 - 2\sqrt{2}$

$3 - 2 \sqrt{2} \: is \: your \: answer$
