18/25x5/46-3/62
`18/25xx5/46-3/62`
`=9/115 - 3/62`
`= 213/7130`
25x5+25x3+..........x25=500
Làm tính chia: (25x5 – 5x4 + 10x2) : 5x2
(25x5 – 5x4 + 10x2) : 5x2
= 25x5 : 5x2 + (-5x4) : 5x2 + 10x2 : 5x2
= (25 : 5).(x5 : x2) + (-5 : 5).(x4 : x2) + (10 : 5).(x2 : x2)
= 5.x5 – 2 + (-1).x4 – 2 + 2.1
= 5x3 – x2 + 2
