(m-n)^2*[(n-m)^3]^5怎么算
5(m-2n)方-3(m+n)+2(m+n)-8(m-2n)方,其中m=-10,n=-6时,怎么算
(2m+3n)(2m-3n)怎么算
(m+n)^3(m+n)^2怎么算?
(n-m)^3×(m-n)^2-(m-n)^5
因式分解(n-m)^3(m-n)^2-(m-n)^5
(3m+2n)(3m+2n-m-n)怎么算
(m-n)·(n-m)2·(m-n)3怎么算?
已知m/n=5、,求(m/(m+n))+(m/(m-n))-(n^2/(m^3-n^2))
初一计算:(m+5n)(m-n)-6(m+2n)(n-3n)?
(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]
