(100 + 67) x 67 + (200 - 33) x 33
= 167 x 67 + 167 x 33
= 167 x ( 67 +33)
= 167 x 100
= 16700

23 x 67 + 63 x 67 + 67 x 14 + 100 x 33
= 67 x (23+63+14) +100 x 33
= 67 x 100 + 100 x 33
= 100 x (67+33)
= 100 x 100
= 10000
tk cho mình nha!
= ( 23 + 63 + 14 ) x 67 + 100 x 33
= 100 x 67 + 100 x 33
= 100 x ( 67 + 33 )
= 100 x 100
= 10 000
Đó chính là đáp án nha bạn. Hok tốt
