M^2+N^2-2N+4M+5=0,则M的负N次方等于多少M^2+N^2-2N+4M+5=0,则M的负N次方等于多少M^2+N^2-2N+4M+5=0,则M的负N次方等于多少M²+N
M^2+N^2-2N+4M+5=0,则M的负N次方等于多少
M^2+N^2-2N+4M+5=0,则M的负N次方等于多少
M^2+N^2-2N+4M+5=0,则M的负N次方等于多少
M²+N²-2N+4M+5=0可化为(M+2)²+(N-1)²=0所以M=-2,N=1,所以M的负N次方=-1/2
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
若m^2+n^2+2m-4n+5=0,则m+n=?
如果m和n互为相反数,则m+2m+3m+4m+5m+5n+4n+3n+2n+n=
.4(m+n)^2*(m+n)^3-7(m+n)(m+n)^4+5(m+n)^5=
(m-n)^2*(m-n)^4=?
设m,n满足m^2+n^2+2m+4n+5=0,求n^m的值
已知|m+2n-5|+(2m+n-1)^2=0,则m^n=?
m^2+4m+n^2-6n+13=0,则m+n=
若m^2+n^2-6n+4m+13=0则m-n=?
m^+4m+n^-2n+5=0,求4m+5n=?
|m-n+2|+(m+n-4)的平方=0则m=(),n=()
m平方+2M+N平方-4N+5=0,求M,N
m*m+n*n-4m+2n+5=0
(m-2n/n-m)-(n/m-n)=
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))
已知3m=2n,则m/(m+n)+n/(m-n)-n^2/(m^2-n^2)=?
已知2m-5n=0,求(1+n/m-m/m-n)/(1-n/m-m/m+n)的值
