Question

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

Answer 1

rationalizezi fractia cu $\sqrt{3} +1$
si vei obtine : $\frac{2( \sqrt{3} +1)}{2}$- $\sqrt{3}$=
(2-ul se simplifica =>  )    = $\sqrt{3} +1 - \sqrt{3}$=1

Answer 2

rationalizezi fractia cu 
si vei obtine : - = 
(2-ul se simplifica =>  )    = =1
