Question

1]calculati folosind factorul comun 309x576+576x894+424x1203       



2]calculati respectand ordinea operatiilor x=70-[16x6+2x{16x3+72:6}-36] :12

Answer 1

309x576+576x894+424x1203=
576(309+894)+424x1203=
576x1203+424x1203=
1203(576+424)=1203x1000=1203000
2)x=70-[16x6+2x{16x3+72:6}-36]:12
x=70-[96+2{48+12}-36}:12
x=70-[96+2·60-36}:12
x=70-[96+120-36]:12
x=70-[216-36]:12
x=70-180:12
x=70-15
x=55
