Efectuati,respectand ordinea operatiilor 4x[27+11x(804-29x13)]-32x18= [(70x8-261)x5+3x(473-11x42)]x10-9x21= 2x{100+7x[300-5x(2730-25x108)]}-37x2x5= 64+{3+5x[29+2x(483-30x160)]}x10+ 6225-2x{5x[2x(107+13)+3x(104+8)]}=

Answer 1

4×[27+11×(804-29×13)]-32×18=
4×[27+11×(804-377)]-576=
4×(27+4697)-576=
4×4724-576=
18896-576=18320

[(70×8-261)×5+3×(473-11×42)]×10-9×21=
[(560-261)×5+3×[473-462)]×10-189=
(299×5+3×11)×10-189=
1528×10-189=
15280-189=15091
