|m+2|+(n-3)^2=0时,则(2m+n)^2010的值是

已知3m=2n,则m/(m+n)+n/(m-n)-n^2/(m^2-n^2)=? 已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2= 若m+n=0,则多项式m^3-m^3n-mn^2+n^3 若|m-n|+(m+2n-3)²=0,则m+n的值是 根号m+2n+6+根号2m+m-3=0,则m+n= (m-n)^3(n-m)^2(m-n)=_____ (3m-n)(m-2n)=() 如果m和n互为相反数,则m+2m+3m+4m+5m+5n+4n+3n+2n+n= 当m-n/m+n=3时,求代数式(3m+3n/m-n)-(m-n/m+n)^2的值为多少? 若／m-3／+（n+2）*（n+2）=0,则m+2n=? |m+2|+(n-3)^2=0时,则(2m+n)^2010的值是 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)) 若(m-2n)/(2m+n)=3,则[3(m-2n)/(2m+n)-(m-2n)/[2(2m+n)] - {9(m-2n)/[4(2m+n)]}的值是? 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 当3m=2n时,分式m/(m+n)+n/(m-n)-n^2 /(m^2-n^2)=? lm+n-3l+m^2n^2+4mn+4=0 求(4m-n)(m-2n)-(n-m）(-m-n) 若(m+n)^2-mn(m+n)=(m+n)·M,则M是（） A.m^2+n^2 B.m^2-mn+n^2 C.m^2-3mn+n^2 D.m^2+mn+n^2
