cứ chép thế ko cần hiểu
15 . 360 + 150 . 2 . 27 + 1500
= 15 . ( 10 . 36 ) + 150 . ( 2 . 27 ) + 150 . 10
= 15 . 10 . 36 + 150 . 54 + 150 . 10
= 150 . 36 + 150 . 54 + 150 . 10
= 150 . ( 36 + 54 + 10 )
= 150 . 100
= 15 000

mình mong các bạn giúp mk
xin cảm ơn

1500:25-1500+1500:76
= 1500 : 25 - 1500 : 1 + 1500 : 76
= 1500 : ( 25 - 1 + 76 )
=1500 : 100
= 15
Tick nha
= 1500 : 25 - 1500 : 1 + 1500 : 76
= 1500 : ( 25 - 1 + 76 )
=1500 : 100
= 15
1500 + ( - 1500 ) = ?
1500+1500=1600+?
\(1500+1500=1600+?\)
\(=3000=1600+?\)
\(?=3000-1600\)
\(?=2400\)
Vậy ? có giá trị bằng 2400 .
