Question

 | 3-√5 | + | √5+√3 | + | √3 - 2 | 

Answer 1

|3-√5 | + | √5+√3 | + | √3 - 2 |= 3- √5 +√5+√3 +2- √3=5

Answer 2

Pai in primul rand discuti modulele.
3-$\sqrt{5}$>0 ===> |3-$\sqrt{5}$| >.0 ====> |...|=3-$\sqrt{5}$
$\sqrt{5}+ \sqrt{3}$>0 ===> |...|=$\sqrt{5} + \sqrt{3}$
|$\sqrt{3} -2$|<0 ====> |...|=2-$\sqrt{3}$
Atunci avem ca : 3-$3- \sqrt{5}+ \sqrt{5} + \sqrt{3}+2- \sqrt{3} =3+2=5$
