-2m^3+24m^-72m求解!
(3m-2n)(3m+2n+1)求解
(m+3m+5m+.+2008m)-(2m+4m+6m+.+2009m)
(m+3m+5m+...+2009m)-(2m+4m+6m+...2008m)
m-2m-3m+4m-5m-6m+7m.2004m=?
计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m)
(m+3m+5m+...+2013m)-(2m+4m+6m+...+2012m)
(m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=?
(m+3m+5m+...+2014m)-(2m+4m+6m+...+2013m)
(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)=
若m为正整数,3^2m*4^2m*36^m/72^2m等于
m+3m+5m+...+2011m-2m-4m-...-2010m等于多少?
(m+3m+5m+...+2009m)-(2m+4m+...+2008m)怎么算
