2^2m+n*16*8^m+(-4^m)*8^m
16^2m/8^2n÷4^m×4^2(n-m+1)
m-2m-3m+4m-5m-6m+7m-8m-9m+.+2002m-2003m-2004m
计算:16-m^2/16+8m+m^2÷m-4/2m+8×m-2/m+2
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)
16-㎡/16+8m+㎡÷m-4/2m+8*m-2/m+2
m+2n=2,3m+4n=8,则m=?,n=?
m+2n=2,3m+4n=8,求m+n=几
m+2n=2且3m+4n=8,求m+n
[(m-n)^2*(m-n)^3]^2/(m-n)^4
因式分解4m^2(m-n)+4n(n-m)
（m-n)2(n-m)3(n-m)4化简
