(m-n)^3(n-m)^2(m-n)=_____
(3m-n)(m-2n)=()
(m-2n/n-m)-(n/m-n)=
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))
(1),(-m-n)(-m+n) (2),(-m+n)(m-n)
已知3m=2n,则m/(m+n)+n/(m-n)-n^2/(m^2-n^2)=?
(m-2n)(-m-n)
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
2m+3n+2m+3n+m+2m+3n+n=______
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
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
若(m+n)(m-n)^2-mn(m+n)=(m+n)·M,则M是
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
