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

= 167 x 67 + 167 x 30 + 161 x 1 + 167 x 2 

= 167 x (67 +30 +1 + 2 )

=167 X 100

= 16 700

_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) (100 + 67) x 67 + (200 - 33) x 33

= 167 x 67 + 167 x 33

= 167 x (67 + 33)

= 167 x 100

= 16700

b) 45,651 x 73 + 45,651 x 20 + 45,651 x 7

= 45,651 x (73 + 20 + 7)

= 45,651 x 100

= 4565,1

c) 14,2 x 30 + 14,2 x 57 + 14,2 x 13

= 14,2 x (30 + 57 + 13)

= 14,2 x 100

= 1420

a) (100 + 67) × 67 + (200 - 33) × 33

= 167 × 67 + 167 × 33

= 167 × 100

= 16700

b) 45,651 × 73 + 45,651 × 20 + 45,651 × 7

= 45,651 × (73 + 20 + 7)

= 45,651 × 100

= 4565,1

c) 14,2 × 30 + 14,2 × 57 + 14,2 × 13

= 14,2 × (30 + 57 + 13)

= 14,2 × 100

= 1420

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

a; (100 + 67) x 0,067 + (200 - 33) x 0,033

= 167 x 0,067 - 167 x 0,033

= 167 x (0,067 + 0,033)

= 167 x 0,1

= 16,7

b; 17,2 x 1,01 - 17 - 0,2

= 17,2 x 1,01 - (17 + 0,2)

= 17,2 x 1,01  - 17,2

= 17,2 x (1,01 - 1)

= 17,2 x 0,01

= 0,172
