4*8^m*16^m=2^9,则m=
m-2m-3m+4m-5m-6m+7m.2004m=?
(m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=?
(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)=
当m=1/2时,求15m²-9-{-4m²+[5m-8m²-(2m²-m)+9m
(m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=?
m-2m-3m+4m-5m-6m+7m-8m-9m+.+2002m-2003m-2004m
4^m+3×8^m÷2^4m+7=16,求m的值
4^m 乘 8^m-1÷2^m=512,则m=_________
4^m乘以8^m-1除以2^m=512,则m=?
若(m)(m)-2m=1,则2m-4m+2008的值是-----------
已知2^m=a,化简16×2^2m-1 ×2^3m-1 -4^m ×8^m
2^m · 4^m · 8^m · 16^m = 2^30 求m的值
