a)2.31.12+4.6.42+8.27.3
b)36.28+36.82+64.69+64.41
a) kết quả là:2400
b)Kết quả là: 11000
Đáp số: 11000
a) 2 x 31 x 12 + 4 x 6 x 42 + 8 x 27 x 3
= 24 x 31 + 24 x 42 + 24 x 27
= 744 + 1008 + 648
= 2400
b) 36 x 28 + 36 x 82 + 64 x 69 + 64 x 41
= 36 x (28 + 82) + 64 x (69 + 41)
= 36 x 110 + 64 x 110
= (36 + 64) x 110
= 100 x 110
= 11000

trieu dang trả lời đúng rùi cho bạn ấy 1 cái đúng nhé
- a. 2.31.12+4.6.42+8.27.3
= 2.12.31 + 2.2.6.42 + 2.4.3.27
= (2.12).31 + (2.2.6).42 + (2.4.3).27
= 24.31 + 24.42 + 24.27
= 24. (31 + 42 + 27 )
= [ Kết quả cậu tự tính nhé ]
- b. 36.28+36.82+64.69+64.41
= [36.(28+82)] + [64.(69+41)]
= 36.100 + 64.110
= 3600 + 6440
= [ kết quả cậu tự tính ]
=> [ k for me ] :)) Mơn :3
