Answer 2

Given : x = 2 - root 3.

$\frac{1}{x} = \frac{1 }{2 - \sqrt{3} } * \frac{2 + \sqrt{3} }{2 + \sqrt{3} }$

                       = $\frac{2 + \sqrt{3} }{4^2 - ( \sqrt{3})^2 }$

                       = $2 + \sqrt{3}$


$x - \frac{1}{x} = 2 - \sqrt{3} - (2 + \sqrt{3} )$

                            = $-2 \sqrt{3}$


Now,

$(x - \frac{1}{x} )^3 = (-2 \sqrt{3} )^3$

                                  = $-24 \sqrt{3}$



Hope this helps!
