Answer 1

Given : x = 2 - √3

To find :  value of (x - 1/x)³

Solution:

x = 2 - √3

1/x = 1/(2 - √3)

Rationalizing

1/x = (2 + √3)/(2 - √3)(2 + √3)

=> 1/x = (2 +√3)/(4 - 3)

=> 1/x = 2 +√3

=> x - 1/x  = 2 - √3 + 2  + √3

=>  x - 1/x  = 4

Cubing both sides

=> (x - 1/x)³ = 4³

=> (x - 1/x)³ = 64

(x - 1/x)³ = 64   if  x = 2 - √3
