若m^2+n^2-m-4n+4/1/4=0,求m^n-mn的值若m^2+n^2-m-4n+4/1/4=0,求m^n-mn的值若m^2+n^2-m-4n+4/1/4=0,求m^n-mn的值m^2+n^2
若m^2+n^2-m-4n+4/1/4=0,求m^n-mn的值
若m^2+n^2-m-4n+4/1/4=0,求m^n-mn的值
若m^2+n^2-m-4n+4/1/4=0,求m^n-mn的值
m^2+n^2-m-4n+4/1/4=0
(m^2-m+1/4)+(n^2-4n+4)=0
(m-1/2)^2+(n-2)^2=0
m=1/2
n=2
m^n-mn=1/4-1=-3/4
若|m|=4,|n|=1/2 1,若m+n>m-n,则m+n=?2,若|m+n|=|m|+|n|若|m|=4,|n|=1/21,若m+n>m-n,则m+n=?2,若|m+n|=|m|+|n|,则m、n的值分别是:
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
(m-n)^2*(m-n)^4=?
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
(m-2n)^2+(3m-n)(2m+2n)-(2m+n)(2m-n) 已知m+n=4 mn=1
已知m的绝对值=2,n的绝对值=1,且m小于n,求/m+n/-/m-n/-/2m+n/+/m+4n/的值
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
m+n/4m^-n^-m-2m/n^-4m^=
.4(m+n)^2*(m+n)^3-7(m+n)(m+n)^4+5(m+n)^5=
若m.n两数之间满足2m-4=(m-5)+(n+1)试比较m,n大小
因式分解4m^2(m-n)+4n(n-m)
4m(m-n)^2+4n(n-m)^3
(n/m+n/2m^2)*4m/n^2
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
4m^2(m+n)-9n^2(m+n)
(m-n)2(n-m)3(n-m)4化简
