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
( 98 x 76 x 101 - 98x 101 x76 ) : ( 2001 x 2002 x ... x 2010 )

tính theo kiểu của các bạn là tính bình thường.
Tính bằng cách hợp lí : c) (98×7676 - 9898×76) ÷ (2001×2002×2003×...×2010)
Đặt (2001×2002×2003×...×2010) = A
= (98x101x76-9898x76): A
= (9898x76-9898x76):A
= 0:A
= 0
