123 . 19 + 123 . 52 + 123 . 29
= 123 . ( 19 + 52 + 29 )
= 123 . 100
= 12300
123( 19 + 52 + 29)
= 123 . 100
= 12300
=123. ( 19 + 52 + 29 )
= 123 . ( 71 + 29 )
= 123 . 100
= 12300
123 . 19 + 123 . 52 + 123 . 29
= 123 . (19 + 52 + 29)
= 123 . 100
= 12300
hihi, tự làm luôn, nha
123.19+123.52+123.29 123.(19+52+29) 123.100=12300
