Nếu x là STN Giải thế này nè bạn
Ta có với x = 6 => 6! + ( 6 + 1)! = 5760 > 840 => x < 6
với x = 0 => 0! + ( 0+1)! = 2 < 840 < Loại >
x = 1 => 1! + ( 1+1)! = 3 < 840 < Loại >
x = 2 => 2! + ( 2+1)! = 8 < 840 < loại >
x = 3 => 3! + ( 3+1)! = 30 < 840 < loại >
x = 4 => 4! + ( 4+1)! = 144 < 840 < loại >
x = 5 => 5! + (5+1)! = 840 < Chọn >
Vậy x = 5

Chúng tôi được sử dụng để giải các bài toán phương trình làm một số phương pháp đại số phổ biến. Nhưng vấn đề bình đẳng cũng có một mẹo khác: thiết lập giới hạn.
Đầu tiên thông báo rằng giai thừa tăng quá nhanh và 840 là số nhỏ và trước tiên bạn có thể kiểm tra ít nhất là nơi X được giới hạn. X phải nhỏ hơn 5, bằng 6! = 720 nhưng 7! = 5040 lớn hơn 840.
Điều đó có nghĩa là bạn có thể thử tất cả các số từ 1 đến 6
x = 1, 1 + 2! = 3
x = 2, 2! +3! = 8
x = 3, 3! +4! = 30
x = 4, 4! +5! = 144
x = 5, 5! +6! = 120 + 720 = 840
Hãy nhớ rằng, không phải tất cả các vấn đề bình đẳng đều được giải quyết bằng cơ chế tìm kiếm chung. Giới hạn cũng là một mẹo hay
