(m-5n)(m-n)-6(m+2n)(m-3n)
初一计算:(m+5n)(m-n)-6(m+2n)(n-3n)?
(m-5n)(m-n)-6(m+2n)(m-3n)
(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、,求(m/(m+n))+(m/(m-n))-(n^2/(m^3-n^2))
m-{n-2m+[3m-(6m+3n)+5n]}=
m-{n-2m+[3m-(6m+3n)-5n]}化简
m方-【5m+3n】【5m-3n】+6【2m-n】【m+2n】等于多少
(m+5n)^2-2(5n+m)(n-3m)+(3m-n)^2
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
计算[5(m+n)2(m-n)]3÷【3(m+n)2(n-m)]2
[5m(3m-n)+2n(n-3m)]/(3m-n)
