Calculati numarul a=([tex] \sqrt{3} + \sqrt{2} [/tex]) X (5-[tex] \sqrt{6} [/tex])+ [tex] (\sqrt{2}-1)^{2} [/tex]-3[tex] \sqrt{3} [/tex]

Răspuns :

[tex] 5\sqrt{3} - \sqrt{18} + 5\sqrt{2} - \sqrt{12} +2-2 \sqrt{2} +1-3 \sqrt{3}=5\sqrt{3} -3\sqrt{2}+5 \sqrt{2} -2 \sqrt{3} +3-2 \sqrt{2} -3 \sqrt{3} =3[/tex]
