(4m^2+9n^2)(3n-2m)(-3n-2m) 请帮我算一下
(4m^2+9n^2)(3n-2m)(-3n-2m) 请帮我算一下
计算 4(m+n)^2*(-m-n)^3-(m+n)(-m-n)^4+5(m+n)^5 请写出步骤...
[(m-n)^2*(m-n)^3]^2/(m-n)^4
(m-n)2(n-m)3(n-m)4化简
(3m-2n)^+(3m+2n) (3m-2n)-9(m+n)^
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
(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)
计算(m+n)^3-(n+m)(m-n)^2
(n-m)^3×(m-n)^2-(m-n)^5
