\(=\frac{2003\cdot2004+\left(2004+1\right)\cdot10+1994}{2004\cdot\left(2005-2003\right)}\)
\(=\frac{2003\cdot2004+2004\cdot10+10+1994}{2004\cdot2}\)
\(=\frac{2003\cdot2004+2004\cdot10+2004}{2004\cdot2}\)
\(=\frac{2004\cdot\left(2003+10+1\right)}{2004\cdot2}\)

Minh ko biet phai gach dau duoi cac chu so ne cac ban giup minh voi nha y nhu la 2011 tren 126 y . Giup minh voi nha ai lam nhanh nhat minh se tik cho ban do nha
2004/2005*2005/2003*2003/2004
help me! Someone help me, I tick for you:ai giúp mình,mình tick cho
so sánh M,N
M=\(\dfrac{2003}{2004}+\dfrac{2004}{2005}\)
N=\(\dfrac{2003+2004}{2004+2005}\)
Tinh tong s=1+2+3+.....+2002+2003+2004
cac ban giup minh nha ! minh tick cho
So sánh
2003/2004+2004/2005+2005/2003 và 3
So sánh
2003/2004 + 2004/2005 + 2005/2003 với 3
2005/2004+2005/2006-2004/2003=??
2005 * 2004 -1/ 2003*2005+2004
So sánh A và B biết:
A = 2003 x 2004 - 1/2003 x 2004
B = 2004 x 2005 - 1/2004 x 2005
