2m-{n+[4m-3(m+2n)]}-5n,
=2m-﹛n+[4m-3m-6n]﹜-5n
=2m-﹛n+m-6n﹜-5n
=2m-m+5n-5n
=m
=2/3
(3m-4n)(4n+3m)-(2m-n)(2m+n)
[(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=5/3,求(m/m+n)+(m/m+n)-(n^2/m^2-n^2)
已知m/n=5、,求(m/(m+n))+(m/(m-n))-(n^2/(m^3-n^2))
2(m-n)^2-(m+n)(m-2n)-3n(n-m) 公因式(n-m)
因式分解:(m+n)^3+2m(m+n)^2+m^2(m+n)
(m+2n)(2m+n)-(3m-n)(m+2n)
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
计算(3-m+n)*(3+m-n)-(2-m+n)*(2+m-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),
(4(m-n)^3)/((n-m)^2)
