2016 x 101 – 2016

= 2016 x 101 – 2016 x 1

= 2016 x ( 101 -1)

= 2016 x 100

= 201600

2017 x ( 101 - 1 ) = 2017 x 100

                            = 201700

 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

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

(100+400)x0x2017=0

500 x 0 x 2017 = 0

(4,329:0,001-43,29).150+2017-5:10

=(4329-43,29).150+2017-0,5

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

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

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

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

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

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

\(2018\cdot2018-2017\cdot2019\)

\(=2018^2-\left(2018-1\right)\left(2018+1\right)\)

\(=2018^2-\left(2018^2-1\right)\)

\(=2018^2-2018^2+1\)

\(=1\)

\(2018.2018-2017.2019\)

\(=2018^2-\left(2018-1\right)\left(2018+1\right)\)

  \(=2018^2-\left(2018^2-1\right)\)

  \(=2018^2-2018^2+1\)

  \(=1\)

nhớ k đấy

2018*2018-2017*2019

=2018*(2019-1)-2017*2019

=2018*2019-2018-2017*2019

=2019-2018=1
