(m+2n)(m-2n)(m²-4n²)
2个回答
(m+2n)(m-2n)(m^2-4n^2)
=(m^2-4n^2)(m^2-4n^2)
=(m^2-4n^2)^2
=m^4-8m^2n^2+16n^4

(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
(n/m+n/2m^2)*4m/n^2
【(m+n)(m-n)-(m-n²)+2n(m-n)】÷4n
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
lm+n-3l+m^2n^2+4mn+4=0 求(4m-n)(m-2n)-(n-m)(-m-n)
(m-2n)^2+(3m-n)(2m+2n)-(2m+n)(2m-n) 已知m+n=4 mn=1
计算1/(m-n)-1/(m+n)-2n/(m^2+n^2)-4n^3/(m^4+n^4)-8n^7/(m^8+n^8)
计算1/(m-n)-1/(m+n)-2n/(m^2+n^2)-4n^3/(m^4+n^4)-8n^7/(m^8+n^8)
若m-2n=4,则4n-2m=,(m-2n)^2-2n+m+5=
化简 (m-n)/(m+2n)+(m^2-n^2)/(m^2+4mn+4n^2)
