Question

value of (x-1/x) , if x = 1 +√2​

Answer 1

Answer:

1

Step-by-step explanation:

when x =1+√2

then .x-1/x =

=> (1+√2-1)/1+√2

=> √2/1+√2

=> 1.

Answer 2

$2-\sqrt{2}\: \:is\: the\: answer.$

Step-by-step explanation:

$Given:( \frac{x - 1}{x} )$

$If \: x = 1 + \sqrt{2} ,$

$Then,( \frac{1 + \sqrt{2} - 1 }{1 + \sqrt{2} } ) =( \frac{ \sqrt{2} }{1 + \sqrt{2} } ) \\ = ( \frac{ \sqrt{2}(1 - \sqrt{2}) }{(1 + \sqrt{2} )(1 - \sqrt{2}) } ) \\ = \frac{ \sqrt{2} - 2}{1 - ({\sqrt{2})}^{2} } \\ = \frac{ \sqrt{2} - 2}{1 - 2} \\ = - ( \sqrt{2} - 2) \\ = 2 - \sqrt{2}$
