Answer 1

Resposta:

Explicação passo-a-passo:

a) 10 : (5 – 4)

= 10:1

= 10

b) 3 + (12 : 4)

= 3+3

= 6

c) (2 + 3) . [5 – (12 : 6)]

= 5. [5 - 2]

= 5.3

= 15

d) 16 : (4 . 4)

= 16:16

= 1

e) (4 . 8) : 2

= 32:2

= 16

f) {[64 : (5 + 3)] . 2} + 4 =

= {[64 : 8].2} + 4

= {8.2} + 4

= 16 + 4

= 20
