Muitissima obrigada pela sua ajuda :⊃

Answer 1

Explicação passo-a-passo:

Resolver as expressões:

a)8+{6:3+[4.2-2.3]+10:2}=

8+{6:3+[8-6]+10:2}=

8+{2+[2]+5}=

8+{4+5}=

8+{9}=

17

b){10:2+[6.3-(4:2-1)+7]-4}=

{10:2+[6.3-(2-1)+7]-4}=

{10:2+[18-(1)+7]-4}=

{10:2+[17+7]-4}=

{10:2+24-4}=

{5+20}=

25

c)6.[4:2+6-(5.2-15:3)+6]=

6.[4:2+6-(10-5)+6]=

6.[2+6-(5)+6]=

6.[8-11]=

6.[-3]=

-18

d)8:4+6.3-8.2-30:6-4.2=

2+18-16-5-8=

20-11-8=

9-8=

1

e)6.3+2.6-10:2-20:2+7=

18+12-5-10+7=

30-5-3=

25-3=

22

f)20:2+6.3-4.8+7.2-4.6=

10+18-32+14-24=

28-46-24=

-18-24=

-42

g)8.6+64:8-72:8-45:3=

48+8-9-15=

56-(-6)=

62

Espero ter ajudado ♥️.
