Răspuns:
- 3 x a - b : 3 + 3 × c = 0
Explicație pas cu pas:
a = (4 + 5 : 5 − 3) : 2
a = (4 + 1 − 3) : 2
a = (5 − 3) : 2
a = 2 : 2
a = 1
b = 11 − 6 : [5 − 4 : (7 − 5 : 1)]
b = 11 − 6 : [5 − 4 : (7 − 5)]
b = 11 − 6 : (5 − 4 : 2)
b = 11 − 6 : (5 − 2)
b = 11 - 6 : 3
b = 11 - 2
b = 9
c = [(8 + 8) : 43] × (9 -3 x 3).
c = [(8 + 8) : 43] × (9 - 9)
c = [(8 + 8) : 43] × 0
c = 0
dacă un factor este 0, tot produsul devine 0
3 x a - b : 3 + 3 × c =
= 3 x 1 - 9 : 3 + 3 × 0 =
= 3 - 3 + 0 =
= 0 + 0 =
= 0
