Ответ:
Решение:
- a) \( (3.8 \cdot 1.75 \div 0.95 - 1.02) \div 2.3 + 0.4 = (6.65 \div 0.95 - 1.02) \div 2.3 + 0.4 = (7 - 1.02) \div 2.3 + 0.4 = 5.98 \div 2.3 + 0.4 = 2.6 + 0.4 = 3 \)
- б) \( (11.28 + 3.4 \div 0.85 \cdot 1.55) \div 4.6 - 0.8 = (11.28 + 4 \cdot 1.55) \div 4.6 - 0.8 = (11.28 + 6.2) \div 4.6 - 0.8 = 17.48 \div 4.6 - 0.8 = 3.8 - 0.8 = 3 \)
Ответ: a) 3, б) 3
