Answer 1

Explicação passo-a-passo:

A) 3³+4²-10×2

3.3.3 + 4.4 - 20

9.3 + 16 - 20

27 + 16 - 20

43 - 20

23

B) (6+2)²+(3×4)²

(6 + 2).(6 + 2) + (3x4).(3x4)

36 +12 +12 +4 +9 +12 +12 +16

48 +16 +21 +28

64 + 49

113

C) 17-(2×3)²

17 - (2x3). - (2x3)

17 + 4 + 6 + 6 + 9

21 + 12 + 9

33 + 9

42

D)(3+2²)²+4÷2

(3+2²).(3+2²) +4÷2

(3+4).(3 + 4) + 2

9 + 12 + 12 + 16 + 2

21 + 28 + 2

49 + 2

51

E) (10÷5)³-2³

(10÷5).(10÷5).(10÷5) - 2³

(2).(2).(2) - 2.2.2

4.(2) - 4.2
