Chúc bạn may mắn...mình chính là Đào Minh Tiến!
\(\left(2012\times99-1006\times198\right)\times2013\)
\(=\left(1006\times2\times99-1006\times198\right)\times2013\)
\(=\left(1006\times198-1006\times198\right)\times2013\)
\(=\left(\left(1006-1006\right)\times198\right)\times2013\)
\(=\left(0\times198\right)\times2013\)
\(=0\)
= ( 2012 x 99 - 1006 x 2 x 99 ) x 2013
= ( 2012 - 1006 x 2 ) x 2013
= ( 2012 - 2012 ) x 2013
= 0 x 2013
= 0
( 2012 x 99 - 1006 x 198 ) x 2013
=( 1006 x 2 x 99 - 1006 x 198 ) x 2013
= ( 1006 x 198 - 1006 x 198 ) x 2013
= 1006 x ( 198-198 ) x 2013
= 1006x 0 x 2013
= 0 x 2013
= 0
