(6n-3m^2)(3m^2+6n)(6n-3m^2)(3m^2+6n)(6n-3m^2)(3m^2+6n)(6n-3m^2)(3m^2+6n)=(6n-3m^2)(6n+3m^2)=(6n)^2-(
(6n-3m^2)(3m^2+6n)
(6n-3m^2)(3m^2+6n)
(6n-3m^2)(3m^2+6n)
(6n-3m^2)(3m^2+6n)=(6n-3m^2)(6n+3m^2)=(6n)^2-(3m^2)^2=36n^2-9m^4
(6n-3m^2)(3m^2+6n)=36n^2-9m^4
36n^2-9m^4
(m-5n)(m-n)-6(m+2n)(m-3n)计算,要有过程
计算(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+4n)(m-n)-6(m+2n)(m-3n),
3m(m+n)-6(m^2-n^2)
m-{n-2m+[3m-(6m+3n)+5n]}=
m-{n-2m+[3m-（6m+3n）-5n]}化简
m方-【5m+3n】【5m-3n】+6【2m-n】【m+2n】等于多少
(6n-3m^2)(3m^2+6n)
(-m^2n^3)^6/(-m^2n^3)等于
.(3m-2n)-(3m+6n+5)
-3/4(-m-n)^6+0.1[-(m+n)^2]^3
计算(3m+2n)(7m-6n)
(3m+2n)(7m-6n)
解方程组:{3分之2(m-n)-4分之m+n=-1,6(m+n)-4(2m-n)=16解方程组:{[2(m-n)/3-(m+n)/4=-1,6(m+n)-4(2m-n)=16不是(m+n)/2-(m-n)/3=1 (m+n)/3-(m-n)/4=-1 你看清楚，是：解方程组:{[2(m-n)/3-(m+n)/4=-1,6(m+n)-4(2m-n)=16
计算[4(m-n)^5-6(m-n)^4+8(m-n)^3]除以2(m-n)
（m-n）^7/（n-m）^6+（-n-m）^3/（m+n）^2急用!
