(1) 原式=[(2)^3]^2m×[ (2)^2]^n÷2^m-n
=2^6m×2^2n÷2^m-n
=2^(6m+2n)÷2^m-n
=2^(6m+2n)-(m-n)
=2^5m+3n
(2)原式=(-2x^6)÷(-x^3)×(-x)
=2x^3×(-x)
=-2x^4
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
【(m+n)(m-n)-(m-n²)+2n(m-n)】÷4n
(1),(-m-n)(-m+n) (2),(-m+n)(m-n)
解关于x的方程:(m+n)(m-n)乘以x^2-4mnx=(m+n)(m-n)..
(n/m+n/2m^2)*4m/n^2
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
4m^2(m+n)-9n^2(m+n)
(m-n)^9乘(n-m)^8/(m-n)^2
因式分解4m^2(m-n)+4n(n-m)
4m(m-n)^2+4n(n-m)^3
(m-n)2(n-m)3(n-m)4化简
(m-2n)(-m-n)
2x+n/m=m/n-(m/n+n/m)x(m+n不等于0)
(m-n)(m-n+2)-8因式分解
化简,1.[(m+n-p)(m+p+n)-(m+n)²]/(-p),2.[(m+n)(m-n)-(m-n)²+2n(m-n)]/4n
(m-n)^2*(m-n)^4=?
