(m-n)4·(n-m)·(n-m)3
计算4(m+n)^2·(-m-n)^3-(m+n)(-m-n)^4+5(m+n)^5
(m-n)2(n-m)3(n-m)4化简
[(m-n)^2*(m-n)^3]^2/(m-n)^4
(3m-4n)(4n+3m)-(2m-n)(2m+n)
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
(m-n)^4+m(m-n)^3-n(n-m)^3 这个怎么因式分解?
计算(m+4n)(m-n)-6(m+2n)(m-3n)
(m+4n)(m-n)-6(m+2n)(m-3n),
(m+4n)(m-n)-6(m+2n)(m-3n)
计算[m+n-4mn/(m+n)]·[m-n+4mn/(m-n)]的正确结果>_
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
(m-n)·(n-m)2·(m-n)3怎么算?
