2. Ifodalarning qiymatini hisoblang: 75 · 10; 100 · 3; 20 · 70; 60 · 90; 5 · (7 · 2); (8 · 2) · 5.

Ko‘paytirishni hisoblaymiz:

1. \(75 \cdot 10 = 750\)
2. \(100 \cdot 3 = 300\)
3. \(20 \cdot 70 = 1400\)
4. \(60 \cdot 90 = 5400\)
5. Avval qavs ichini hisoblaymiz: \(5 \cdot (7 \cdot 2) = 5 \cdot 14 = 70\).
6. Avval qavs ichini hisoblaymiz: \((8 \cdot 2) \cdot 5 = 16 \cdot 5 = 80\).

Javob: 750; 300; 1400; 5400; 70; 80.
