m=?时,3/m-8=1/4+5?

当m=1/2时,求15m²-9-{-4m²+[5m-8m²-(2m²-m)+9m²]-3m} (m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)= m-2m-3m+4m-5m-6m+7m.2004m=? (m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=? 先化简,再求值：当=1/2时,求15㎡-9-｛-4m²+[5m-8m²-(2m²-m)]-3m}的值 (m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=? m=?时,3/m-8=1/4+5? 当m= 时,2m(3m-5)+3m(1-2m)=14 [(m-3)/(m+5)]^2+[(4-2m)/(m+5)]^2=1,求m 计算(m+3m+5m……+2009m)—(2m+4m+6m+2008m)= 计算：（m+3m+5m+…+2015m）-(2m+4m+6m+…+2014m)= 计算（m+3m+5m+.+2009m)-(2m+4m+6m+.+2010m)=多少 (m+3m+5m+...+2011m)-(2m+4m+6m+...+2012m)=多少 计算：(m+3m+5m+…+2011m)-(2m+4m+6m+…+2010m)= (m+3m+5m+...+2011m)-(2m+4m+6m+...+2012m)=多少 计算(m+3m+5m+...+2011m)-(2m+4m+6m+...+2010m)= 化简求值m^2(m+4)+2m(m^2 -1)-3m^3,其中m=2/5 化简求值m^2(m+4)+2m(m^2 -1)-3m^3,其中m=2/5
