• Masalan, a) A: «5 — tub son» — (R); B: «5 >6» — (Y) bo’lsin, u holda A∧B: «5 — tub son va u 6 dan katta» — yolg’on mulohaza bo’ladi.
• b) A: «3<8» —(R),B: «8< 11» — (R), A∧B: «3 <8∧8< 11» yoki «3<8< 11», ya’ni tengsizliklar konyunksiyasini qo’sh tengsizlik ko’rinishida yozish mumkin va aksincha; ta’rifga ko’ra «3 <8 < 11» — rost mulohaza.

Mulohazalar konyunksiyasining xossalari:

• Mulohazalar konyunksiyasining xossalari:
• 1°. A∧B = B∧A(kommutativlik);
• 2°. (A∧B)∧C = A∧(B∧C) = A∧B∧C(assotsiativlik);
• 3°. A∧ = Y (A∧ — aynan yolg’on mulohaza).
• Mulohazalar konyunksiyasi xossalarining to’g’riligini
• rostlik jadvallari tuzish va mos kataklardagi murakkab
• mulohazalar qiymatlarini taqqoslab tekshirish mumkin.

• Rost mulohazalarni ko’chiring, yoniga ularning inkorini yozing.
