复数z=x^2-2x-3+{[(log(1/2)(x)]^2-log(1/2)(x)-2}i是虚部为正数的非纯虚数,求实数x的范围
(log(1/2)(x)是log以(1/2)为底的x
复数z=x^2-2x-3+{[(log(1/2)(x)]^2-log(1/2)(x)-2}i是虚部为正数的非纯虚数,求实数x的范围(log(1/2)(x)是log以(1/2)为底的x
由x^2-2x-3!=0得:x!=1和3.
由log(1/2)(x)^2…>0得:
log(1/2)(x)2
得:x>2或0
[log(4)(2x)][log(2x)(3y)][log(3y)(z)]=log(8x)[(8x)]^2,则z=?
log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解,求每步详...log(2x)+log(3y)-log(2z) 怎么化简?log3(x^2-2x-6)=2 log(3x+6)=1+log(x)求解,
2log(m)y-log(m)x-log(m)z

已知复数Z=log(2)(X^2-3X-2)+ilog(2)(X-3)(1) 当X为何实数时,Z为实数?(2) 当X为何实数时,Z为纯虚数?(3) 当X为何实数时,Z在复平面上对应的点位于第三象限?(log后面的2为下标,我打不来.- -)
若log底数2[log底数3(log底数4)]若log底数2[log底数3(log底数4(x))]=log底数3[log底数4(log底数2(y))]=log底数4[log底数2(log底数3z)]=0,则x+y+z=
