1.(15n^3/6m)/(45n/2m^2)*(-"3n/m^2")
1.(15n^3/6m)/(45n/2m^2)*(-"3n/m^2")
初一计算:(m+5n)(m-n)-6(m+2n)(n-3n)?
计算(m+4n)(m-n)-6(m+2n)(m-3n)
(m+4n)(m-n)-6(m+2n)(m-3n),
(m-5n)(m-n)-6(m+2n)(m-3n)
(m+4n)(m-n)-6(m+2n)(m-3n)
[(m-n)^2*(m-n)^3]^2/(m-n)^4
(m-n)2(n-m)3(n-m)4化简
计算(m+n)^3-(n+m)(m-n)^2
(n-m)^3×(m-n)^2-(m-n)^5
因式分解(n-m)^3(m-n)^2-(m-n)^5
3m(m-n)-2n(m-n)的平方
