k mik nha
( 1 + 3 + 5 + 7 + ..... + 2001).(135 135.137 - 135.137 137)
=( 1 + 3 + 5 + 7 + ..... + 2001).( 135.1001.137 - 135.1001-137)
=( 1 + 3 + 5 + 7 + ..... + 2001). 0
= 0

các bn ơi k mik nha
Xin lỗi Phạm Thị Thanh Huyền mình chỉ được chọn 1 _~_
Ta có:
\(\left(1+3+5+7+...+2001\right).\left(135135.137-135.137137\right)\)
\(=\left(1+3+5+7+...+2001\right).\left(18513495-18513495\right)\)
\(=\left(1+3+5+7+...+2001\right).0\)
\(=0\)
Chúc bạn học tốt !!!
(1+3+5+7+...+2001)x(135135x137-137137x135)
