Question

$| 2 - \sqrt{3} | + \frac{1}{2 - \sqrt{3} }$

Answer 1

aduci la acelasi numitor( adica amplifici numarul din modul cu 2-$\sqrt{3}$)...si iti rezulta ca $\frac{( 2- \sqrt{3} )^{2} +1 }{2- \sqrt{3} }$...$\frac{4-4 \sqrt{3}+3+1 }{2- \sqrt{3} }$.....$\frac{4(1- \sqrt{3}+1) }{2- \sqrt{3} }$....$\frac{4(2- \sqrt{3)} }{2- \sqrt{3} }$..se simplifica parantezele si iti da 4
