Answer 1

Resposta:

Bons estudos ❤

Explicação passo-a-passo:

a) 5² : (5 +1 -1)+ 4 x 2 =

25: 5 + 8

5+8

13

b) (3 +1)² +2 x 5 - 10⁰

${4}^{2} + 10 - 1 \\ 16 + 9 \\ 25$

c) 3² : (4 – 1) + 3 x 2² =

9 : 3 + 3 × 4

3 + 12

15

d) 70 – [5 x (2² : 4) + 3²] =

70 - [ 5× ( 4 : 4 ) + 9]

70 - [ 5× 1 + 9]

70 - [ 5 + 9 ]

70 - 14

56

e) (7 + 4) x (3² - 2³) =

11 × (9-8)

11× 1

11

f) 5² + 2³ - 2 x (3 + 9) =

25 + 8 - 2 x 12

33 - 24

9

g) 6² : 3² + 4 x 10 – 12 =

36 : 9 + 40 - 12

4 + 40 - 12

44 - 12

32

h) (7² - 1) : 3 + 2 x 5 =

(49- 1) ÷ 3 + 10

48 ÷ 3 + 10

16 + 10

26
