Ответ:
- \(3258 \cdot 46 = 3258 \cdot (40 + 6) = 130320 + 19548 = 149868\).
- \(704 \cdot 69 = 704 \cdot (70 - 1) = 49280 - 704 = 48576\).
- \(4107 \cdot 38 = 4107 \cdot (40 - 2) = 164280 - 8214 = 156066\).
- \(5672 \cdot 870 = 5672 \cdot 87 \cdot 10 = 493464 \cdot 10 = 4934640\).
- \(3524 \cdot 346 = 3524 \cdot (300 + 40 + 6) = 1057200 + 140960 + 21144 = 1219304\).
- \(608 \cdot 605 = 608 \cdot (600 + 5) = 364800 + 3040 = 367840\).
