Question

1) Resolva as expressões


a) (9-3+(40×2)-70÷7)2)




b) [ (17+2×2)÷3+6×4 ]÷4



c) (5+3)×12÷(5-3)×4

Answer 1

Olá, as resoluções ficam as seguintes:

A) (9 - 3 + (40 * 2) - 70/7)2
(9-3+(40*2)-70/7)2
(9-3+80-70/7)2
(6+80-10)2

76*2 = 152


B) [(17 + 2 * 2) / 3 + 6 * 4]/4
[(17 + 2 * 2) / 3 + 6 * 4]/4
[21 / 3 + 6 * 4]/4
[7 + 6 * 4]/4
[7 + 24]/4
31/4 = 7,75


C) (5+3)*12/(5-3) * 4
(5+3)*12/(5-3) * 4
8*12/(5-3)*4
8*12/2*4
96/2*4
48*4 = 192
