Question

(3737x 50- 5050 x 36): (1+2+3+........+99+100)

Answer 1

(3737x 50- 5050 x 36): (1+2+3+........+99+100)

= (37 . 101 . 50 - 50 . 101 . 36) : \(\frac{100.\left(100+1\right)}{2}\)

= 50 . (37 . 101 - 101 . 36) : 5050

= 50 x 101 - 5050

= 5050 - 5050

= 0

Answer 2

Từ dòng thứ 4 sửa lại :

= 50 x 101 : 5050

= 5050 : 5050

= 1
