= 2015 x ( 3 + 6 + 1 )
= 2015 x 10
= 20150
2016 x ( 111 - 11 )
= 2016 x 100
= 201600
tk mình nhé
thank you very much
bye bye
2015x3+2015x6+2015
= 2015 x ( 3+6+1 )
= 2015 x 10
= 20150
2016x111-11x2016
= 2016 x ( 111-11)
= 2016x100
= 201600
2015*3 + 2015*6+ 2015 2016* 111- 11* 2016
=2015*( 3+6+1) = 2016*( 111-11)
=2015* 10 = 2016* 100
= 20150 = 201600
tk cho mk nhe
