(5m^2n^-2)^2*3m^-3n^3
(5m^2n^-2)^2*3m^-3n^3
(5m^2n^-2)^2*3m^-3n^3
原式=25m^4n^(-4)*m^(-3)n^3
=25m^(4-3)n^(-4+3)
=25mn^(-1)
=25m^4n^(-4)×3m^(-3)n³
=75mn^(-1)
=75m/n
因式分解(n-m)^3(m-n)^2-(m-n)^5
(n-m)^3×(m-n)^2-(m-n)^5
m/n=5/3,求(m/m+n)+(m/m+n)-(n^2/m^2-n^2)
已知m/n=5、,求(m/(m+n))+(m/(m-n))-(n^2/(m^3-n^2))
(m+5n)^2-2(5n+m)(n-3m)+(3m-n)^2
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
[5m(3m-n)+2n(n-3m)]/(3m-n)
5(m+n)(m-n)-2(m+n)平方-3(m-n)平方
(m-5n)(m-n)-6(m+2n)(m-3n)计算,要有过程
(m-5n)(m-n)-6(m+2n)(m-3n)
(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=
因式分解m^5-m^3n-m^2+n,
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
