2017 * 101 + 2017

= 2017 * 101 + 2017 * 1

= 2017 * ( 101 + 1 )

= 2017 * 102

= 2017 * 100 + 2017 * 2

= 201700 + 4034

= 205734

ko bít có chép sai đầu bài ko

nếu thuận tiện như sau:

2017x101-2017

=2017x(101-1)

=2017x100

=201700

còn như đầu bài ra thì 

2017x101+2017

=2017x(101+1)

=2017x102

=205734

** mk nha

2017 x 101 + 2017

= 2017 x 101 + 2017 x 1

= 2017 x ( 101 - 1 )

= 2017 x 100

= 201700

 2014 x 2016 + 2017

=4060224+2017

=4062241

(100+400)x0x2017=0

500 x 0 x 2017 = 0

giúp mik với :<

2017 x 3 + 2017 x 31 + 2017 x 67 - 2017 = 2017 x ( 3 + 31 + 67 - 1 )

                                                            = 2017 x 100

                                                            = 201700

tk mk nha

= 2017 *(3+31+67)-2017

=2017 * 101 - 2017

=201700

2017 x 3 + 2017 x 31 + 2017 x 67 - 2017

=  2017 x ( 3 + 31 + 61 - 1 )

= 2017 x 94 

= 189598

\(\frac{2017}{2018}\times2015+\frac{2017}{2018}\times4-\frac{2017}{2018}.\)

\(=\frac{2017}{2018}\times2015+\frac{2017}{2018}\times4-\frac{2017}{2018}\times1\)

\(=\frac{2017}{2018}\times\left(2015+4-1\right)\)

\(=\frac{2017}{2018}\times2018\)

\(=\frac{2017\times2018}{2018\times1}\)

\(=\frac{2017}{1}=2017\)

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

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

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

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

\(=2016\times1\)

\(=2016\)

nhanh nhất là trả lời luôn: 2016

thank

2017+2017 x 7 +2017 x 2
