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
= 11 000
k mình nha !
=36 x(28+82) +64x(69+41)
=36x110+64x110
=(36+64)x110
=100x110=11000
easy
Trả lời :
36 x (28 + 82) + 64 x (69 + 41)
= 36 x 110 + 64 x 110
= 3960 + 7040
= 11000
