(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
(m-2n)(2n+m)-(-3m-4n)(4n-3m)
=m^2-4n^2+16n^2-9m^2
=-8m^2+12n^2
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
4m(m-n)^2+4n(n-m)^3
(m-n)2(n-m)3(n-m)4化简
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
(3m-4n)(4n+3m)-(2m-n)(2m+n)
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
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),
(1),(-m-n)(-m+n) (2),(-m+n)(m-n)
(m-2n)(-m-n)
2(m+n)2-(m+n)+4(m+n)-(m+n)2+3(m+n)2 化简求值
(m-n)(m^5+m^4n+m^3n^2+m²n^3+mn^4+n^5)
2(m+n)2²-(m+n)+4(m+n)-(m+n)²+3(m+n)² 计算
计算4(m+n)^2·(-m-n)^3-(m+n)(-m-n)^4+5(m+n)^5
