  1. ~ Bạn tham khảo ~
    x – 897 = ( 10-7)^3 . ( 20-3)+60-4^2
    x – 897 = 3^3 . 17 + 60 – 16
    x – 897 = 27.17+44
    x-897=459+44
    x-897=503
    x=503 + 897
    x=1400

  2. ~ Bạn tham khảo ~
    x-897 = (10-7)^3 * (20-3)+60-4^2
    => x-897 = 3^3 * 17+60-16
    => x-897 = 27 * 17 + 60 – 16
    => x – 897 = 459 + 44
    => x – 897 = 503
    => x = 503 + 897
    => x = 1400
    Vậy x=1400
