约掉 m^3n^2 就可以了:-1/12 mn - 2/3 n^3 + 1/9
(m-n)2(n-m)3(n-m)4化简
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
(m-n)(m^5+m^4n+m^3n^2+m²n^3+mn^4+n^5)
计算4(m+n)^2·(-m-n)^3-(m+n)(-m-n)^4+5(m+n)^5
计算 4(m+n)^2*(-m-n)^3-(m+n)(-m-n)^4+5(m+n)^5 请写出步骤...
计算4(m+n)^2乘(-m-n)^3-(m+n)(-m-n)^4+5(m+n)^5
.4(m+n)^2*(m+n)^3-7(m+n)(m+n)^4+5(m+n)^5=
4m(m-n)^2+4n(n-m)^3
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
化简:[3m^(n+4)+2m^(n+1)]/[3m^(n-1)]-[m^3-1/3][m^3+3]
-5m(-m+3n)+4m(-4m-5/2n),其中m=2,n=-1
化简-3(m-n)²-(m-n)平方-3(m-n)+4m-n)的平方+2(m-n)-1
如果m和n互为相反数,则m+2m+3m+4m+5m+5n+4n+3n+2n+n=
如果m,n互为相反数,求m+2m+3m+4m+5m+5n+4n+3n+2n+n=多少
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
(m-2n)^2+(3m-n)(2m+2n)-(2m+n)(2m-n) 已知m+n=4 mn=1
1/(m-n)-1/(m+n)-2n/(m^2+n^2)-4n^3/m^4+n^4)-8n^7/(m^8+n^8)-16n^15/(m^16+n^16)+32n^31/(n32-m32)
