  1. C_1: (54 xx 63) : 9
    = 3402 : 9
    = 378
    C_2: (54 xx 63) : 9
    = 54 : 9 xx 63 : 9
    = 6 xx 7
    = 42
    C_1: (45 + 17) xx 32
    = 62 xx 32
    = 1984
    C_2: (45 + 17) xx 32
    = 45 xx 32 + 17 xx 32
    = 1440 + 544
    = 1984

  2. C1 : (54 x 63) : 9
    =3402 : 9
    =378
    C2: (54 x 63) : 9 
    =54:9×63:9
    = 6 × 7
    = 42
    Đề sai rồi bn ak
    C1 :(45+17) x 32
    =62 × 32
    =1984
    C2 : 
    (45+17) x 32
    =45 × 32 + 17× 32
