已知复数Z=log(2)(X^2-3X-2)+ilog(2)(X-3)
已知复数Z=log(2)(X^2-3X-2)+ilog(2)(X-3)
log(2x)+log(3y)-log(2z) 怎么化简? log3(x^2-2x-6)=2 log(3x+6)=1+l
已知log(2)[log(3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x
log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4)
1.已知z=x+yi,且z乘以共轭复数z+(1-2i)z+(1+2i)共轭复数z=3,求|z|的最大值,和复数z的实部与
一、已知f(x)=log底下2(x^2+2x+5),g(x)=log底下1/2(x^2-3x+2)
已知复数Z满足|Z|^2-2|Z |-3=0,则复数Z的对应点Z(x,y)的轨迹是?
1/log(2)x+1/log(3)x+1/log(4)x=1,x=?
已知复数z=x+yi,且/Z-2/=根号3则y/x的最大值为
已知复数z=x+yi,且/z-2/=根号3,则y/x的最大值是多少?
已知集合 U={x|log以1/3底(x^2-3x+5)的对数>-2,x属于Z},
已知log(1/7)[log(3)(log(2)x)]=0
