Đặt (2001×2002×2003×...×2010) = A
= (98x101x76-9898x76): A
= (9898x76-9898x76):A

sssssssssssssssssdddddddddddddddddddddddddddddddddddaaaaaaaaaaaaaaaaaaaaaaaaa
a)(44x52x60):(11x13x15) =(44:11)x(52:13)x(60:15)=4x4x4 =64
\(a.\)
\(\left(44.52.60\right):\left(11.13.15\right)=\frac{44.52.60}{11.13.15}\frac{4.4.4\left(11.13.15\right)}{\left(11.13.15\right)}=4^3=64\)

**** cho mình nha
( 98 x 7676 - 9898 x 76 ) : ( 2001 x 2002 x........x 2010)
=(98x101x76-98x101): ( 2001 x 2002 x........x 2010)

=0
tich dung cho minh nha
(98*7676-9898*76)/(2001*2002*...*2010)
=(98*101*76-101*98*76)/(2001*2002*...*2010)
=0/(2001*2002*...*2010)=0
