  1. Giải đáp:
    25×37+49×25+86×75
    = 25×(37 + 49) + 86 ×75
    = 25× 86 + 86 ×75
    = 86 × (25 + 75)
    = 86 × 100
    = 8600
    37×112+63×101-11×37
    = 37×(112 – 11) + 63 × 101
    = 37× 101 + 63 × 101
    = 101×(37 + 63)
    = 101× 100
    = 10100
    35×101+100×65
    = 35 ×( 100 + 1 )+ 100 × 65
    = 3500 + 35 + 6500
    = 10000 + 35
    =10035
    Câu cuối theo mik sửa đề là
    17×40+83×40
    = 40×(17+ 83)
    = 40× 100
    = 4000

  2. @Thỏ
    25 times 37 + 49 times 25 + 86 times 75
    = 25 times 37 + 49 times 25 + 86 times 25 times 3
    = 25 times (37 + 49 + 86 times 3)
    = 25 times (86 + 86 times 3)
    = 25 times [86 (1 + 3)]
    = 25 times [86 times 4]
    = 25 times 86 times 4
    = (25 times 4) times 86
    = 100 times 86
    = 8600
    37 times 112 + 63 times 101 – 11 times 37
    = 37 times (112-11) + 63 times 101
    = 37 times 101 + 63 times 101
    = 101 times (37 + 63)
    = 101 times 100
    = 10100
    35 times 101 + 100 times 65
    = 3535 +  6500
    = 10035
