Dau coroana!Aici chiar nu imi da rezultatul .Greșesc undeva dar nu stiu unde exact

Answer 1

a)5-2-rad(4-3)=3-1=2

b)(18-12):(5rad3 - 3rad3) =

6:2rad3=6rad3:6=rad3

c)[(2-2rad6+3)-(8-4rad6+3)]•(6+2rad6)+12=

(5-2rad6-11+4rad6)(6+2rad6)+12=

(-6+2rad6)(6+2rad6)+12=

(2-6rad6)(2+6rad6)+12=

4-216+12=

-200

d)1-2-rad3-(1-2+rad3)=

-1-rad3+1-rad3=

-2rad3
