Gọi số đó là : abcd . Số mới là 1abcd . Ta có :
1abcd = abcd . 6
10000 + abcd = abcd . 6
10000 = abcd . 5 ( Rút gọn đi ở cả hai vế 1 số abcd )
abcd = 10000 : 5
abcd = 2000
Vậy số đó là : 2000.
Đáp số : 2000.

25-45=16=36
5^2-2.5.9/2+(9/2)^2-(9/2)^2= 4^2-2.4.9/2+(9/2)^2-(9/2)^2
(5-9/2)^2 -(9/2)^2 = (4-9/2)^2-(9/2)^2
(5-9/2)^2=(4-9/2)^2
5-9/2=4-9/2
5=4
