If `|z|ge3,` then determine the least value of `|z+(1)/(z)|`.

1. If |z-2+i|≤ 2 then find the greatest and least value of | z|

If |z+4| le 3 , then the maximum value of |z+1| is

If z is any complex number such that |z+4|lt=3, then find the greatest value of |z+1|dot

If z is a complex number such that |z| ge 2 , then the minimum value of |z+(1)/(2)| .

Find the gratest and the least values of |z_(1)+z_(2)|, if z_(1)=24+7iand |z_(2)|=6," where "i=sqrt(-1)

If |z_(1)| = 1, |z_(2)| =2, |z_(3)|=3, and |9z_(1)z_(2) + 4z_(1)z_(3)+ z_(2)z_(3)|= 12 , then find the value of |z_(1) + z_(2) + z_(3)| .

If |z-(4)/(z)|=2 then the maximum value of |z| is

If |z|=1 and z ne pm 1 , then all the values of (z)/(1-z^(2)) lie on

If z^(2)+z+1=0 , where z is a complex number, then the value of (z+(1)/(z))^(2)+(z^(2)+(1)/(z^(2)))^(2)+(z^(3)+(1)/(z^(3)))^(2)+....+(z^(6)+(1)/(z^(6)))^(2) is

If z is a complex number such that |z|=1, z ne 1 , then the real part of |(z-1)/(z+1)| is
