2017 x 7 - 2017 x 4 - 2017 x 3 + 2017
=2017.(7-4-3)
=2017.0
=0
\(2017\times7-2017\times4-2017\times3+2017\)
\(=2017\times(7-4-3+1)\)
\(=2017\times1=2017\)
2017*7 - 2017*4 - 2017*3 +2017 = 2017
2017x(7-4-3)+2017
=2017x0+2017
=0+2017
=2017
hihihihi
2017 x 7 - 2017 x 4 - 2017 x 3 + 2017
= 2017 x (7 - 4 - 3 + 1)
= 2017 x 1
= 2017
2017 x 7 - 2017 x 4 - 2017 x 3 + 2017
= 2017 x (7 - 4 - 3 + 1)
= 2017 x 1
= 2017
2017x7-2017x4-2017x3+2017
=2017x(7-4-3)+2017
=2017x0+2017
=0+2017
=2017
chế mỏi tay nên chỉ đáp số thôi heng= 2017
2017 x 7 - 2017 x 4 - 2017 x 3 + 2017
= 2017 x [ 7 - 4 - 3 ] + 2017
= 2017 x 0 + 2017
= 0 + 2017
= 2017
mk làm bài này nhiều rùi nên lm cũng dễ
