Question

Calcule o valor das expressões numérica:
a) 5 + 3 x 8 - 4:
b) 2 + 2 x 5 - 8:
c) 25 + 2 - 6 / 3 - 5 + 1:
d) 45 / 3 + 2 x 9:
e) 5 x 8 + 1 - 6 / 3:
f) 7 x 6 + 8 - √149:

Answer 1

Resposta:

a) 25

b) 4

c) 21

d) 33

e) 39

f) 37.8

Explicação passo a passo:

5 + (3 x 8) - 4=25

5+24-4=25

2 + (2 x 5) - 8=4

2+10-8=4

25 + 2 - (6 / 3) - 5 + 1=21

25+2-2-5+1=21

(45 / 3) + (2 x 9)=33

15+18=33

(5 x 8) + 1 - (6 / 3)=39

40+1-2=39

(7 x 6) + 8 - (√149)=37.8

42+8-12,2=37,8
