1.符号有点不明确,希望可以确认一下.
2.原式=1+(-1/8)^2011*8^2011
=1-8^-2011*8^2011
=0
3.原式=6a^mn-9a^n*b^n+10a^m*b^m-15b^mn
消不掉,能再看下题么?
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))
因式分解m^5-m^3n-m^2+n,
(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=
(1),(-m-n)(-m+n) (2),(-m+n)(m-n)
[(m-n)^2*(m-n)^3]^2/(m-n)^4
