ko bt đúng ko !

bạn có tham khảo thôi nhé !

Bằng  \(\frac{987}{155}\). Chắc 100% luôn

Các bạn tk mình nhé! ^-^

a. 8 x 17 x 125 

= 8 x 125 x 17 

= 1000 x 17 

= 17000

b. 35 x 34 + 35 x 36 + 65 x 75 + 65 x 45 

= 35 x (34 + 36 ) + 65 x ( 75 + 45 )

= 35 x 70 + 65 x 120 

= 2450 + 7800

= 10250

c 4 x 7² + 16 x 2² 

= 4 x 49 + 16 x 4 

= 4 x ( 49 + 16)

= 4 x 65

= 260
