若(9^m+3) ×(27^m+1)÷(3^4m+7)=81,求m
m-2m-3m+4m-5m-6m+7m.2004m=?
若(2+根号3)^^m=1,求m²-1/m+1-m²-m/根号m²-2m+1的值
(1)已知9(m+3)*27(m+1)/3(4m+7)=81,求m的值(2)若5m=32,5n=11,求5(3m-2n)
已知:3^3×(9^m+4)÷(27^2m-1)=729,求m的值
计算:(m+3m+5m+…+2015m)-(2m+4m+6m+…+2014m)=
已知(9^m)×(27^m)×(81^m)=3^18,求m的值
已知9的m+3次方×27的m+1次方÷3的4m+7次方=81,求m的值.
若m*m-3m+1=0,求分式2m*m+2\m*m的值,
9^m *27^m*81^m=3 ^18求m
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)=?
4^m+3×8^m÷2^4m+7=16,求m的值
