Respuesta:
1) a . b = 20 ∧ a = - 5 ⥤ b = -4
2) lal = 7 ∧ a < 0 ⥤ a = -7
3) a - b = 7 ∧ a = 2 ⥤ b = -5
4) a : b = 1 ∧ a = - 6 ⥤ b = -6
5) a . b = 0 ∧ a = - 5 ⥤ b = 0
6) a² = 25 ∧ a < 0 ⥤ a = -5
7) a + b = 12 ∧ a = 20 ⥤ b = -8
Explicación paso a paso:
1) a . b = 20 ∧ a = - 5 ⥤ b = -4
2) lal = 7 ∧ a < 0 ⥤ a = -7
3) a - b = 7 ∧ a = 2 ⥤ b = -5
4) a : b = 1 ∧ a = - 6 ⥤ b = -6
5) a . b = 0 ∧ a = - 5 ⥤ b = 0
6) a² = 25 ∧ a < 0 ⥤ a = -5
7) a + b = 12 ∧ a = 20 ⥤ b = -8
