已知m为整数,若分式3m-2分之6m 也为整数,则整数m的值为0或1或2.
6m/(3m-2) = 2 + 4/ (3m-2)
∣3m-2∣≤4 -2/3≤ m≤2,6,6m/(3m-2)
=(6m-4+4)/(3m-2)
=2+4/(3m-2)
若分式3m-2分之6m 也为整数
则m=1,或m=2,1,6m/3m-2=k (k是整数)
6m=3mk-2k
m=2k/3k-6
m=2,0,
6m/(3m-2) = 2 + 4/ (3m-2)
∣3m-2∣≤4 -2/3≤ m≤2,6,6m/(3m-2)
=(6m-4+4)/(3m-2)
=2+4/(3m-2)
若分式3m-2分之6m 也为整数
则m=1,或m=2,1,6m/3m-2=k (k是整数)
6m=3mk-2k
m=2k/3k-6
m=2,0,
