me ajudem é pra agora por favorrrrrrrrr​

Answer 1

Resposta:

a)20-(15+6÷3)=

20-(15+2)=

20-17=3

b)(7+2)×(3-1)=

9×2=18

c)15+[6+(8-4÷2)]=

15+[6+(8-2)]=

15+[6+6]=

15+12= 27

d) 40-[3+(10-2)÷2]=

40-[3+8÷2]=

40-3+4= 41

e) 180÷{10+2×[20-45÷(13-2×5)]}=

180÷{10+2×[20-45÷(13-10)]}=

180÷{10+2×[20-45÷3]}=

180÷{10-2×[20-15]}=

180÷{10-2×5}=

180÷{10-10}=

180÷0=180
