Bạn ơi giải giúp mình câu này. 50:[3(5² - 4x6) +2]
Mình gửi đáp án:

`4/5xx3/7+4/5xx6/7-4/5xx4/14`
`= 4/5xx6/14+4/5xx12/14-4/5xx4/14`
`=4/5xx(6+12-4)/14`
`=4/5xx14/14`
`=4/5xx1`
`= 4/5`
trả lời:
4/5x3/7+4/5x6/7-4/5x4/14
=(4/5 x 3/7) + (4/5 x 6/7) − (4/5 x 4/14)
=4/5 x (3/7 + 6/7 − 4/14)
=4/5 x 7/7
= 4/5 x 1
= 4/5
`4/5 xx 3/7 + 4/5 xx 6/7 - 4/5 xx 4/14`
`= 4/5 xx ( 3/7 + 6/7 - 4/14 )`
`= 4/5 xx ( 9/7 - 2/7 )`
`= 4/5 xx 7/7`
`= 4/5 xx 1`
`= 4/5.`
