  1. ~ Bạn tham khảo ~
    a, 10xx5+10xx4+10xx8
    = 10xx(5+4+8)
    = 10xx17
    = 170
    b, 7 xx 5 + 7 xx8
    = 7 xx( 5+8)
    = 7 xx 13
    = 91

  2. a) 10 xx 5 + 10 xx 4 + 10 xx 8
    = 10 xx ( 5 + 4 + 8)
    = 10 xx 17
    = 170
    b) 7 xx 5 + 7 xx 8
    = 7 xx (5 + 8)
    = 7 xx 13
    = 91
