24 . ( 16 - 5 ) - 16 . ( 24 - 5 )
= 24 . 16 - 24 . 5 - 16 . 24 - 16 . 5
= -24 . 5 - 16 . 5
= -40 . 5
= -200
24 . ( 16 - 5 ) - 16 . ( 24 - 5 )
= 24 . 16 - 24 . 5 - 16 . 24 - 16 . 5
= 24 . ( 16 - 5 ) - 16 . ( 24 - 5 )
= 24 . 11 - 16 . 21
= ( 24 - 16 ) . ( 11 - 21 )
= 8 . - 10
= - 80
24 . ( 16 - 5 ) - 16 . ( 24 - 5 )
= 24 . 16 - 24 . 5 - 16 . 24 + 16 .5
= 24 . ( 16 - 16) - 5 ( 24 -16 )
= 24 . 0 - 5 . 8
= 0 - 40
= - 40
Nhầm mình sửa lại nha:
24 . ( 16 - 5 ) - 16 . ( 24 - 5 )
= 24 . 16 - 24 . 5 - 16 . 24 - 16 . 5
= 24 . ( 16 - 16 ) - 5( 24 - 16 )
= 24 . 0 - 40
= 0 - 40
= - 40
