Завдання:
Не обчислюючи, заміни зірочку знаком >, < або =, щоб утворилася правильна рівність або нерівність:
1) 41 ⋅ (–3) ⋅ (–5) ⋅ (–6) * 0;
2) 0 * –11 ⋅ (–2) ⋅ (–19) ⋅ (–12) ⋅ 25;
3) 17 ⋅ (–5) ⋅ (–13) * –2 ⋅ 19 ⋅ 23;
4) 12 ⋅ (–13) ⋅ 14 ⋅ 0 * 15 ⋅ (–16) ⋅ (–17) ⋅ 0.
Розв'язок:
1) 41 ⋅ (-3) ⋅ (-5) ⋅ (-6) < 0
2) 0 < -11 ⋅ (-2) ⋅ (-19) ⋅ (-12) ⋅ 25
3) 17 ⋅ (-5) ⋅ (-13) > -2 ⋅ 19 ⋅ 23
4) 12 ⋅ (-13) ⋅ 14 ⋅ 0 = 15 ⋅ (-16) ⋅ (-17) ⋅ 0
