Question

if root 2=1.414,then the value of 1/root 2+1 is ?? plzz answer my question............

Answer 1

Answer:

Step-by-step explanation:

Given that, √2 = 1.414 and we need to find the value of √(√2 - 1/√2 + 1)

We first rationalize the equation and we will get,

√[(√2 - 1)^2/(√2 + 1)(√2 - 1)]

=> √[(√2-1)^2/(2-1)]

=> (√2 - 1 )  

here we apply the value of √2 and we will get

1.414 - 1 = 0.414

Therefore, the value of √(√2-1/√2+1) is 0.414.

Answer 2

Answer:

here is your answer mate...

Step-by-step explanation:

(1/ √2 + 1 ) * ( √2 - 1 / √2 - 1 )  

= √2 - 1/(√2)² - ( 1 )²

= √2 - 1 / 2-1

= √2 -1 / 1

= √2 - 1

= 1.414 - 1

= 0.414
