ajutati - ma si pe mine va rog la ex 51

Answer 1

a) 156 x (10 + 2)=156 x 10+ 156 x 2= 1560 +312=1872

236 x (10+8)= 236 x 10 + 236 x 8 = 2360+1888=4248

19 x (250+ 3)= 19 x 250 + 19 x 3 = 4750+57= 4807

47 x (120 + 9) = 47 x 120 + 47 x 9 = 5640 + 423 = 6063

b) 360 x (20 +3) = 360 x 20 +360 x 3 = 7200 + 1080 = 8280

602 x (10+6) = 602 x 10 + 602 x 6 =6020 + 3612 = 9632

28 x (250 + 7) = 28 x 250 + 28 x 7 = 7000 + 196 = 7196

81 x (40 + 9) = 81 x 40 + 81 x 9 =3240 + 729 =3969
