Question

Calcule o valor das expressões numéricas:

a) 2³ : 4 + 3² =

b) 7² + 2 . [ ( 3² - 4 . 1³ )] =

c) (30 – 5 . 6) : (7 + 2 . 10) =

d) 3² + (8 . 5 + 2³ - 5¹ ) =

e) [( 24 : 8) + 5 . 3] + 2 =

f) [( 18 + 3 . 2) : 8 + 5 . 3] =

g) ( 2² + 5²) + ( 3 . 2 + 4) =​

Answer 1

a) 2³ ÷ 4 + 3²

8 ÷ 4 + 9

2 + 9

11

b) 7² + 2 × [(3² - 4 × 1³)]

49 + 2 × (9 - 4 × 1)

49 + 2 × (9 - 4)

49 + 2 × 5

49 + 10

59

c) (30 - 5 × 6) ÷ (7 + 2 × 10)

(30 - 30) ÷ (7 + 20)

0 ÷ 27

0

d) 3² + (8 × 5 + 2³ - 5¹)

9 + (40 + 8 - 5)

9 + 43

52

e) [(24 ÷ 8) + 5 × 3] + 2

[3 + 15] + 2

18 + 2

20

f) [(18 + 3 × 2) ÷ 8 + 5 × 3]

[18 + 6] ÷ 8 + 15

24 ÷ 8 + 15

3 + 15

18

g) (2² + 5²) + (3 × 2 + 4)

(4 + 25) + (6 + 4)

29 + 10

39
