若t=[(4m^2)/(m+2)]-2 (m>=2 or m=2 or m答案是t>=2或t
若t=[(4m^2)/(m+2)]-2 (m>=2 or m=2 or m
答案是t>=2或t
若t=[(4m^2)/(m+2)]-2 (m>=2 or m=2 or m答案是t>=2或t
当m=2时
t=[(4m^2)/(m+2)]-2
=(4*2^2)/(2+2)-2
=2
当m大于2时,t大于2
所以当m>=2,t>=2
另一个值暂时想不出来
若t=[(4m^2)/(m+2)]-2 (m>=2 or m=2 or m答案是t>=2或t
(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)=
m-2m-3m+4m-5m-6m+7m.2004m=?
(m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=?
(m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=?
如果m=2n=3t,那么n/m*t/m的值是多少?
若m^2+m=1,则2m^4+2m^3+2m+2012
若(m)(m)-2m=1,则2m-4m+2008的值是-----------
已知集合M={1,2,t},N={t^2+3t-3,1},若M∪N=M,求t
已知m={1,t},n={t∧2－t+1},若m并n=m,求t的取值集合.
化简并求值 m*m*m-2m*m+m除以m*m*m-m 其中m=2011
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)=
