化简2(4m^2n^2-3n^3)+5(-3m^2n^2+4n^3)
(m-n)2(n-m)3(n-m)4化简
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
计算4(m+n)^2·(-m-n)^3-(m+n)(-m-n)^4+5(m+n)^5
计算4(m+n)^2乘(-m-n)^3-(m+n)(-m-n)^4+5(m+n)^5
计算 4(m+n)^2*(-m-n)^3-(m+n)(-m-n)^4+5(m+n)^5 请写出步骤...
(n-m)^3×(m-n)^2-(m-n)^5
因式分解(n-m)^3(m-n)^2-(m-n)^5
(3m-4n)(4n+3m)-(2m-n)(2m+n)
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)
