Answer 1

Resposta:

a) (12 + [8 × (19 - 5) - 10])=

(12 + [8 × 14 - 10])=

(12 + 102)=

114

b) 6 (3+ [(93 - 22) + 2])=

6 (3+ [71 + 2])=

6 (3+ 73)=

6 (76)=

456

d) 50 - 4 (35 - 5 - 3)=

50 - 4 (27)=

50-108

-58

c) [49 - (6 x 6 - 15) + 7]=

[49 - (36 - 15) + 7]=

[49 - 21 + 7]=

35

g) 50+ 10+ [12 - (2 x 5-3)]=

50+ 10 + [12 - (10-3)]=

50+ 10 + [12 - 7]=

50+ 10 + 5=

65

e) 17+ [24 = (3 + 1) × 8] - 9=​

17+ [24 + 4 × 8] - 9=​

17+ [24 + 36] - 9=​

17+ 60- 9=​
