|m-n|=n-m,|m|=4|n|=3,则|(m+n)|^2=_______?

|m-n|=n-m,|m|=4|n|=3,则|(m+n)|^2=_______? m,n互为相反数,则（3m-2n)-(2m-3n)=_______. 已知3m=2n,则m/(m+n)+n/(m-n)-n^2/(m^2-n^2)=? 若(m-2n)/(2m+n)=3,则[3(m-2n)/(2m+n)-(m-2n)/[2(2m+n)] - {9(m-2n 如果m和n互为相反数,则m+2m+3m+4m+5m+5n+4n+3n+2n+n= 已知m/n=5、,求（m/（m+n）)+(m/(m-n))-(n^2/(m^3-n^2)) n=m/M 已知2m+n分之m-2n=3,则2m+n分之3(m-2n)+3(2m+n）分之m-2n-4（2m+n）分之5（m-2n） 1,已知3m=4n,则m/m+n +n/m-n -m^2/m^2-n^2= m+2n=2,3m+4n=8,则m=?,n=? 先化简,在求值(m+n)(m-n)(-m^2-n^2)-（-2m+n)(-2m-n)(4m^2+n^2) 其中m=1,n 如果m,n互为相反数,求m+2m+3m+4m+5m+5n+4n+3n+2n+n=多少
