(b)
638 x 176 - 638 x 75 - 638
(c) 85 x 15 + 15 x 15
(d) 688 x 10 x 437 - 6880 x 337
(e) 125 x 8 x 883 + 117 x 25 x 40
(1) 750 x 17 + 750 x 38 + 27 x 750 + 18 x 750​

Answer 1

Answer:

$(1)1562 \times (62 + 38) = 1562 \times 100 = 156200 \\ (3)15 \times (85 + 15) = 15 \times 100 = 1500 \\ (4)6880 \times 437 - 6880 \times 337 = 6880 \times (437 - 337) = 6880 \times 100 = 688000 \\ (5)25 \times 5 \times 8 \times 883 + 117 \times 25 \times 8 \times 5 = 25 \times 8 \times 5 \times (117 + 883) = 1000 \times 1000 = 1000000$
