  1. 1988 x 1996 + 1997 + 1995 = 3972040
    1997 x 1996 – 1995 x 1996 = 3992
    3972040/ 3992 rút gọn bằng : 995/1 = 995
    Chúc bn hok tốt!!!
     

  2. $\frac{1988 x 1996 + 1997 + 1995}{1997 x 1996 – 1995 x 1996}$ = $\frac{3968048 + 1997 + 1995}{3986012 – 3982020}$ = $\frac{3972040}{3992}$ = 995= 3992
    Học tốt!
