Question

Resolva as seguintes expressões numéricas: a) 8 ⋅ (12 + 8 ⋅ 6) : (7 ⋅ 15 − 5 ⋅ 17) b) (36 : 12 ⋅ 8 ) + (2 ⋅ 45 : 5) c) 100 ⋅ {42 + 2 ⋅ [30 + 48 : (24 : 6)]} : 2 + 15

Answer 1

Resposta:

a) 8 ⋅ (12 + 8 ⋅ 6) : (7 ⋅ 15 − 5 ⋅ 17)

8 . (12 + 48) : (105 - 85)

8 . 60 : 20

8 . 3 = 24

b)  (36 : 12 ⋅ 8 ) + (2 ⋅ 45 : 5)

(3 . 8 ) + ( 2 . 9)

24 +  18 = 42

c) 100 ⋅ {42 + 2 ⋅ [30 + 48 : (24 : 6)]} : 2 + 15

100. {42 + 2 . [ 30 + 48 : 4 ]} : 2 + 5

100. { 42 + 2 . [ 30 + 12]} : 2 + 5

100 . { 42 + 2 . 42}: 2+ 5

100 . { 42 + 84} : 2+ 5

100.  126 : 2 + 5

12.600 : 2 + 5

12. 600 : 7 = 1.800
