**** bn hiền

36 x ( 28 + 82 ) + 64 x ( 69 + 41 ) = ( 36 + 64 ) x (28 + 82) = 100 x 110 = 11000
36 * 28 + 36 * 82 + 64 * 69 + 64 * 41=?
nhớ ghi các bước tính và cách giải rõ ràng
36 * 28 + 36 * 82 + 64 * 69 + 64 * 41
= 36 * ( 28 + 82 ) + 64 * ( 69 + 41 )
= 36 * 110 + 64 * 110
= 110 * ( 36 + 64 )
= 110 * 100
= 11000
bài này âm rồi nha,tính kĩ rồi nha
sai đề rồi bạn ạ
a) 2 . 31 . 12 + 4 . 6 . 42 + 8 . 27 . 3
b) 36 . 28 + 36 . 82 + 64 . 69 . 64 . 41
b) 36.28+36.82+64.69+64.41
= 36.(28+82)+64.(69+41)
=36.110+64.110
=(36+64).110
=100.110
=11000.( phần a mk nghĩ sau )
b) = 36 . (28+82) + 64 . (69+41)
= 36 . 110 + 64 . 110
= (36+64) . 110
= 100 . 110
= 11000
a, 2 . 31 . 12 + 4 . 6 . 42 + 8 . 27 . 3
= 2 . 31 . 3 . 4 + 4 . 2 .3 . 42 + 2 . 4 . 27 . 3
= 2 . 3 . 4 ( 31 + 42 + 27 )
= 2 . 3 . 4 . 110
= 2640

Ai cmt thì cmt luôn cách làm nhé =)))
