设m,n满足m^2+n^2+2m+4n+5=0,求n^m的值设m,n满足m^2+n^2+2m+4n+5=0,求n^m的值设m,n满足m^2+n^2+2m+4n+5=0,求n^m的值m^2+n^2+2m
设m,n满足m^2+n^2+2m+4n+5=0,求n^m的值
设m,n满足m^2+n^2+2m+4n+5=0,求n^m的值
设m,n满足m^2+n^2+2m+4n+5=0,求n^m的值
m^2+n^2+2m+4n+5=0
(m+1)^2+(n+2)^2=0
所以(m+1)^2=0,(n+2)^2=0
所以m+1=0,n+2=0
m=-1,n=-2
n^m=(-2)^(-1)=-1/2
原式=m^2+2m+1+n^2+4n+4=0
(m+1)^2+(n+2)^2=0
m=-1 n=-2
n^m=(-2)^(-1)=-1/2
（m+1）^2+(n+2)^2=0
=>m=-1,n=-2
n^m=-1/2
设m,n满足m^2+n^2+2m+4n+5=0,求n^m的值
设m,n是有理数,并且m,n满足m^2+2n+n√2=17-4√2,求m+n的平方根
(1),(-m-n)(-m+n) (2),(-m+n)(m-n)
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
(m-2n)(-m-n)
若有理数m,n满足m-2n=4,2m-n=3,则m+n等于
(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)
因式分解4m^2(m-n)+4n(n-m)
4m(m-n)^2+4n(n-m)^3
（m-n)2(n-m)3(n-m)4化简
设M,N为正整数,且M>N.求证：（M-N）/(ln M - ln N ) < （M+N）/2
设M,N为正整数,且M>N.求证：（M-N）/(ln M - ln N ) < （M+N）/2
设m,n为自然数,且满足：n^2=m^2+167,求m,n的值
