(m^4-81)/(3+m)/(9+m^2)因式分解
(m^4-81)/(3+m)/(9+m^2)因式分解
(m^4-81)/(3+m)/(9+m^2)因式分解
=(m^2-9)(m^2+9)/(3+m)(9+M)^2
=(m-3)(m+3)/(3+m)
=m-3
m-3
m^4-81=(9+m^2)*(m^2-9)
m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m求m的值
计算:m-2m-3m+4m-5m-6m+7m-8m-9m+...+2002m-2003m-2004m
m-2m-3m+4m-5m-6m+7m-8m-9m+.+2002m-2003m-2004m
(m^4-81)/(3+m)/(9+m^2)因式分解
计算:81^m×27^m-9²×9^m×3^5m-4
计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2008m)
(m+3m+5m+...+2009m)-(2m+4m+6m+...2008m)
(m+3m+5m+...+2014m)-(2m+4m+6m+...+2013m)
(m+3m+5m+...+2013m)-(2m+4m+6m+...+2012m)
(m+3m+5m+...+2015m)-(2m+4m+6m+...+2014m)=
计算:(m+3m+5m+...+2009m)-(2m+4m+6m+...+2010m)
m-2m-3m+4m-5m-6m+7m.2004m=?
(m+3m+5m.+2013m)-(2m+4m+6m+.+2012m)=?
已知9^(m+3)×27^(m+1)÷3^(4m+7)=81 求m
(3m的立方-4m平方+m)/m-m
当m=1/2时,求15m²-9-{-4m²+[5m-8m²-(2m²-m)+9m²]-3m}
3^m * 9^m * 81^m * 6 * 561^m =3^30 求m=?
若3^m*9^m*27^m*81^m=3^30,则m=帮下忙!
