= (1-2015).(2-2015)....(2015-2015)....(2029-2015).(2030-2015)
= (1-2015).(2-2015)....0....(2029-2015).(2030-2015)
= 0
= (1-2015).(2-2015)....(2015-2015)....(2029-2015).(2030-2015)

Thực hiện phép tính( tính hợp lí-nếu có thể )
(1^2015-101^2015).(2^2015-100^2015).(3^2015-99^2015). ..... .(101^2015-1^2015)
2, Tính S= (12015 - 1012015).(22015 - 1002015).(32015 - 992015). ....... . (1002015 - 12015)
Tinh:
S=2015 + 2015/1+2 +2015/1+2+3 + 2015/1+2+3+4 +... + 2015/1+2+3+...+2016
Tinh:
S=2015 + 2015/1+2 +2015/1+2+3 + 2015/1+2+3+4 +... + 2015/1+2+3+...+2016
so sanh m=(2015^37+37^2015+1)/2015^38 va n=(2015^38+37^2015+2)/2015^39
(12015-1012015)*(22015-1002015)*(32015-992015)... (1012015-12015)
Giúp mk điiiiiiiiiiiiiiii
2015 + (2015/ 1+2) + (2015/ 1+2+3) +......+ (2015/ 1+2+3+...+2014) =?
Tính tổng S= 2015 + 2015/1+2 + 2015/1+2+3 + ... + 2015/1+2+3+...+2016
Tính tổng S=2015+2015/1+2+2015/1+2+3+..........+2015/1+2+3+........+2016
