若|m+1/3|+(n-1/2)^2=0,求多项式m^2+2m^3n+n^2-2m^2-2m^3n+3n^2的值若|m+1/3|+(n-1/2)^2=0,求多项式m^2+2m^3n+n^2-2m^2-
若|m+1/3|+(n-1/2)^2=0,求多项式m^2+2m^3n+n^2-2m^2-2m^3n+3n^2的值
若|m+1/3|+(n-1/2)^2=0,求多项式m^2+2m^3n+n^2-2m^2-2m^3n+3n^2的值
若|m+1/3|+(n-1/2)^2=0,求多项式m^2+2m^3n+n^2-2m^2-2m^3n+3n^2的值
绝对值和平方都大于等于0
相加等于0,若有一个大于0,则另一个小于0,不成立.
所以两个都等于0
所以m+1/3=0,n-1/2=0
m=-1/3,n=1/2
m^2+2m^3n+n^2-2m^2-2m^3n+3n^2
=-m^2+4n^2
=-1/9+1
=8/9
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
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互为相反数 则3[m-n]-1/2[2m-10n]=?
如果m-3n+4=0 求(m-3n)^2+7m^3-3(2m^3n-m^2n-1)+3(m^3+2m^3n-m^2n+n
已知实数m,n,若m>=0,n>=0,m+n=1,则m^2/(m+2)+n^2/(n+1)的最小值为
(1),(-m-n)(-m+n) (2),(-m+n)(m-n)
已知|m-1|+|m+2n|=0 求试|m-n|+|m+n|快
若(3m-2n+1)与|5m=2n-n|互为相反数,求m+n的值
若|m-3|+n^2-4n+4=0求[(2m+n)^2-3(m+n)(m-n)-4n^2]/(-1/4m)的值今天就要
(2m+n)(2m-n)+n(2m+n)-8m^2n^3/(2n^3) m=-2分之1,n=2013
若2M=2N 求分式(1+m/n-n/n-m)除以(1-(m/n)-n/n+m)
若2M=2N 求分式(1+m/n-n/n-m)除以(1-(m/n)-n/n+m)
(m-2n)^2+(3m-n)(2m+2n)-(2m+n)(2m-n) 已知m+n=4 mn=1
已知2m-5n=0,求(1+(n/m)-(n/m-n))除以(1-(n/m)-(m/m+n))的值
已知2m-5n=0,求(1+(n/m)-(n/m-n))除以(1-(n/m)-(m/m+n))的值 急不要网上抄的
已知2m-5n=0,求(1+(n/m)-(n/m-n))除以(1-(n/m)-(m/m+n))的值.关键是解题的思路,
已知2m-5n=0,求(1+(n/m)-(n/m-n))除以(1-(n/m)-(m/m+n))的值
