b) a+b=7√7-4√6+√7+3√2=(7+1)√7-4√2*√3+3√2=8√7+(3-4√3)√2

b-a=√7+3√2-7√7+4√6=-6√7+3√2+4√2√3=-6√7+(3+4√3)√2
c)a+b=2√11+3+7-5√11= (2-5)√11+10=10-3√11

b-a=7-5√11-2√11-3=4-7√11

d)a+b=2√3-3+(-5-3√3)=2√3-3-5-3√3=(2-3)√3-8=-1√3-8

b-a=-5-√3-2√3+3=-2-3√3

ita-te ca le-am rescris si inclus si punctul b
unde?
aa gata
am dat reincarcati
da, trebuie dat refresh la pagina ca am dat edit pe text
