Answer 2

Răspuns:

a) 20

b) 30

c) 20

d) 10

e) 0

f) 0

Explicație pas cu pas:

a) | -4 | + | 5 | + | -11 | = 4 + 5 + 11 = 9 + 11 = 20

b) | -27 | - | -13 | + | 16 | = 27 - 13 + 16 = 14 + 16 = 30

c) | -14 | × | -2 | - | -8 | = 14 × 2 - 8 = 28 - 8 = 20

d) | 28 | ÷ | -14 | + | 8 | = 28 ÷ 14 + 8 = 2 + 8 = 10

e) (| -2 |)^8 ÷ (| 2 |)^6 - (| -2 |)^2 = 2^8 ÷ 2^6 - 2^2 = 2^2 - 2^2 = 0

f) (| 5 - 2 |)^2 ÷ | -3 | - | -3 | = 3^2 ÷ 3 - 3 = 3^2 ÷ 0 = 0
