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
2017*3+2017*31+2017*67-2017
=2017*(3+31+67)-2017
=2017*101-2017
=201700
ĐS:201700
=\(2017\times\left(3+31+67-1\right)\)
=\(2017\times100\)
=201700
2017*3+2017*31+2017*67-2017
=2017*(3+31+67-1)
=2017*100
=201700
k mik nha
2017 x 3 + 2017 x 31 + 2017 x 67 - 2017
= 2017 x (3 + 31 + 67 - 1)
= 2017 x 100
= 201 700
= 2017 x ( 3 + 31 + 67 - 1 )
= 2017 x 100
= 201700
mk trả lời nhanh đúng đó tk cho mình nha
