(3^3)*(9^m)+4/[27^(2m-1)]=729,求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)=
(1m+3m+5m+...+2009m)-(2m+4m+6m+...=2008m)
若m*m-3m+1=0,求分式2m*m+2\m*m的值,
已知:3^3×(9^m+4)÷(27^2m-1)=729,求m的值
若已知m^2-4m*3=1,求1-m^2+4m
已知m²+2m+1=0,求m³+2m²+3m
已知m>4,化简|m-4|+|7-2m|+|m×m-2m+1|-|m×m-2m-3|
(m+3m+5m+7m+.+2009m)-(2m-4m-6m-.-2008m)=?
m-2m-3m+4m-5m-6m+7m-8m-9m+.+2002m-2003m-2004m
已知m+m分之一=1,求m(m+3)+(1+2m)(1-2m)的值
