  1. Giải đáp + Lời giải và giải thích chi tiết:
    571 xx ( 40 – 7 )
    = 571 xx 33
    = 18843
    456 xx ( 20 – 6 )
    = 456 xx 14
    = 6384
    107 xx ( 30 + 5 )
    = 107 xx 35
    = 3745
    326 x ( 20 + 7 )
    = 326 xx 27
    = 8802

  2. a) 571 × (40 – 7)
    = 571 × 33
    = 18843
    b) 107 × (30 + 5)
    = 107 × 35
    = 3745
    c) 456 × (20 – 6)
    = 456 × 14
    = 6384
    d) 326 × (20 + 7)
    = 326 × 27
    = 8802
