16700!!!

(100 + 67) x 67 + (200 - 33) x 33 

 = 167 x 67 + 167 x 33

 = 167 x ( 67 +33)

 = 167 x 100 

 = 16700

chính xác là 16700

_Chúc bạn học tốt_

  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

Tui trả lời đầu tiên nè 

a: \(=167\cdot\dfrac{67}{1000}+167\cdot\dfrac{33}{1000}=167\cdot\dfrac{1}{10}=\dfrac{167}{10}\)
