HELLO DEAR,given, x = 2 + √3 . AND 2x = 2(2 + √3)
Now, we have to find (√2x + 1/√2x)=?
now, on squaring of (√2x + 1/√2x)²
(√2x + 1/√2x)² = (2x + 1/2x + 2*√2x * 1/√2x)
now put the values of 2x , 1/2x
(√2x + 1/√2x)² = [2(2 + √3) + (2 - √3)/2 + 2]
(√2x + 1/√2x)² = [(8 + 4√3 + 2 - √3)/2 + 2]
(√2x + 1/√2x)² = (10 + 3√3+4)2
(√2x + 1/√2x) =
(√2x + 1/√2x) =
I HOPE ITS HELP YOU DEAR,
THANKS
