Answer 1

Explicație pas cu pas:

a) 6×14-2×(40-27:3)=

6×14-2×(40-9)=

6×14-2×31=

84-62=22=

b)1012-5×(9:3×3+202:2)=

1012-5×(9+101)=

1012-5×110=

1012-550=

462

c)(6×14-2)×(40-27:3)=

82×31=

2542

d[(2×3²+3×2²):6+5²]:5+10²=

[(2×9+3×4):6+25]:5+100=

[(18+12):6+25]:5+100=

(30:6+25):5+100=

30:5+100=

6+100=106
