Answer 1

Bom dia!!

Resolva de dentro para fora:

a) 120+{560:[40+(300:10)]-19}=

120+{560:[40+(30)]-19}=

120+{560:[70]-19}=

120+{80-19}=

120+61=181

b)28×[6×(42:3-9)]=

28×[6×(14-9)]=

28×[6×5]=

28×30=840

c)360:[100-(50-6+3+4)]=

360:[100-(51)]=

360:(49)=7,35

d)(36-54:9)×2=

(36-6)x2=

30×2=60

e)(64:8-2×3)×10=

(8-6)×10=

2x10=20

f)46+[5+(42:6-4)]

46+[5+(7-4)]

46+[5+3]

46+8=54
