2016(34+63+2+1)=2016*100=201600

= 2016 x (34 + 63 +2 +1) =2016 x 100 =201600

CHO MÌNH HỎI CÁI DẤU KIA LÀ GÌ VẬY BẠN

2016 x 72 + 2016 x 29 – 2016

=(2016-2016) x (72 + 29) 

=  0  x  101=0

\(2016\times72+2016\times29-2016=2016\times72+2016\times29-2016\times1=2016\times\left(72+29-1\right)=2016\times10=201600\)

2016 x 72 + 2016 x 29 - 2016

= 2016 x (72 + 29 - 1)

= 2016 x 100

= 201600

 2014 x 2016 + 2017

=4060224+2017

=4062241

\(2017\times2001-2016\times2001-2000\)
\(=2017\times2001-2001-2016\times2000\)

\(=2001\times\left(2017-1\right)-2016\times2000\)

\(=2001\times2016-2016\times2000\)

\(=2016\times\left(2001-2000\right)\)

\(=2016\times1\)

\(=2016\)

nhanh nhất là trả lời luôn: 2016

giúp mình nhanh với ạ
