Răspuns:
a) [tex]1 + (2 + \sqrt{3} ) = 3 + \sqrt{3}[/tex]
b) [tex]4 - (3 + \sqrt{2} ) = 1 - \sqrt{2}[/tex]
c) [tex]7 + (\sqrt{5} - 7) = \sqrt{5}[/tex]
d) [tex]3^{2} - (\sqrt{11} + 9) = - \sqrt{11}[/tex]
e) [tex]1 + \sqrt{2} + 2\sqrt{3} + (-3\sqrt{2} ) + (-4\sqrt{3} ) = 1 - 2\sqrt{2} - 2\sqrt3}[/tex]
f) [tex](3\sqrt{5}- 5) + 7 + ( -2\sqrt{5} - 6) + \sqrt{5} + 4 = 2\sqrt{5}[/tex]
Sper ca te-am ajutat!
