﹙3/2m-n﹚-2m-n/﹙2m-n﹚²等于
﹙3/2m-n﹚-2m-n/﹙2m-n﹚²等于
﹙3/2m-n﹚-2m-n/﹙2m-n﹚²等于
﹙3/2m-n﹚-2m-n/﹙2m-n﹚²
=3/(2m-n)-1/(2m-n)
=2/(2m-n)
﹙3/2m-n﹚-2m-n/﹙2m-n﹚²等于
最简公分母3/2m-n,3m-n/﹙2m-n﹚²
计算4﹙m√n/m+2/n√mn³﹚-3﹙n√m/n+m/1√m³n﹚=
(1),(-m-n)(-m+n) (2),(-m+n)(m-n)
(m-2n)(-m-n)
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
3m(m-n)-2n(m-n)的平方
因式分解(n-m)^3(m-n)^2-(m-n)^5
(m-n)2(n-m)3(n-m)4化简
(n-m)^3×(m-n)^2-(m-n)^5
计算(m+n)^3-(n+m)(m-n)^2
(m-n)^3(n-m)^2(m-n)=_____
4m(m-n)^2+4n(n-m)^3
m-n+2n^2/(m+n)
2(m-n)的2次-(m+n)(m-2n)-3n(n-m)
2m-3n-m+2n
