  1. X=” c11/28 × 12/30 × 13/22 ×14/26
    X=132/840× 13/22×14/26×15/32×16/24
    X=1716/18480×14/26×15/32×16/24
    X=24024/480480×15/32×16/24
    X=360360/15375360 × 16/24
    X=5765760/369008640

  2. X = 11/28 x 12/30 x 13/22 x 14/26 x 15/32 x 16/24
    X = 132/840 x 13/22 x 14/26 x 15/32 x 16/24
    X = 1716/18480  x 14/26 x 15/32 x 16/24
    X = 24024/480480 x 15/32 x 16/24
    X = 360360/15375360 x 16/24
    X = 5765760/369008640
    Vậy X bằng 5765760/369008640
    XIN HAY NHẤT Ạ!!!!!
