m方-【5m+3n】【5m-3n】+6【2m-n】【m+2n】等于多少
m方-【5m+3n】【5m-3n】+6【2m-n】【m+2n】等于多少
5m+2n-3m+ n 等于多少?
(n-m)^3×(m-n)^2-(m-n)^5
因式分解(n-m)^3(m-n)^2-(m-n)^5
已知m/n = 5/3 求m/(m+n)+m/(m-n)-n^2/(m^2-n^2)等于多少?(要化简全过程)
(m-5n)(m-n)-6(m+2n)(m-3n)
5(m-2n)方-3(m+n)+2(m+n)-8(m-2n)方,其中m=-10,n=-6时,怎么算
初一计算:(m+5n)(m-n)-6(m+2n)(n-3n)?
已知m/n=5、,求(m/(m+n))+(m/(m-n))-(n^2/(m^3-n^2))
如果m,n互为相反数,求m+2m+3m+4m+5m+5n+4n+3n+2n+n=多少
(m-n+3)(m+n-2)等于多少
(m+5n)^2-2(5n+m)(n-3m)+(3m-n)^2
