Question

1/ 1+ root 2 pls answer my q plsssssss

Answer 1

Rationalizing the equation,

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

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

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

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

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

-1+$\sqrt{2}$

$\sqrt{2}$ - 1 is the required answer
