(m-n)^3(n-m)^2(m-n)=_____
(3m-n)(m-2n)=()
若2m-n/m+2n=5,求3(2m-n)/m+2n-m+2n/2m-n+3的值
若2m-n/m+2n=5,求3(2m-n)/m+2n-m+2n/2m-n+3的值
若2m=3n,求分式(1+m/n-n/n-m)除以(1-m/n-n/n+m)的值
若2m=3n,求分式(1+m/n-n/n-m)除以(1-m/n-n/n+m)的值
已知3m=2n,则m/(m+n)+n/(m-n)-n^2/(m^2-n^2)=?
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
m/n=5/3,求(m/m+n)+(m/m+n)-(n^2/m^2-n^2)
已知m/n=5、,求(m/(m+n))+(m/(m-n))-(n^2/(m^3-n^2))
若(m-2n)/(2m+n)=3,则[3(m-2n)/(2m+n)-(m-2n)/[2(2m+n)] - {9(m-2n)/[4(2m+n)]}的值是?
1若m=n,则|m|=|n|;2若m=—n,则|m|=|n|;3若|m|=|n|,则m=—n;4若|m|=|n|,则m=n哪个对
若(m+n)^2-mn(m+n)=(m+n)·M,则M是() A.m^2+n^2 B.m^2-mn+n^2 C.m^2-3mn+n^2 D.m^2+mn+n^2
若有理数m,n满足m-2n=4,2m-n=3,则m+n等于
若|m-n|=n-m,且|m|=4、|n|=3,则(m+n)^2=
若|m-n|=n-m,且|m|=4,|n|=3,则(m+n)^2=?
2m+3n+2m+3n+m+2m+3n+n=______
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
