Question

if x =2+√3 then x ³+1/x³ is​

Answer 1

Answer:

$x = 2 + \sqrt{3}$

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

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

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

$\frac{1}{x} = \frac{2 - \sqrt{3} }{4 - 3}$

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

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

Now,

$= {x}^{3} + \frac{1}{ {x}^{3} }$

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

$= 8 + 3 \sqrt{3} + 12 \sqrt{3} + 18 + 8 - 3 \sqrt{3} - 12 \sqrt{3} + 18$

$= 8 + 18 + 8 + 18$

$= 52$
