for a complex number z, Show that |z|=0<=>z=0

If z is a complex number,show that |z|^(2)=|z^(2)|

The number of complex numbers z such that |z-1|=|z+1|=|z-i|, equals (1)1(2)2(3), (4) 0

The number of complex numbers z such that |z-1|=|z+1|=|z-i| is

The number of complex numbers z such that |z|=1 and |(z)/(bar(z))+(z)/(z)|=1 is (arg(z)in[0,2 pi)) then 4 b.6c.8d .m or ethan8

Find the complex number z such that z^(2)+|z|=0

Find the complex number z such that z^2+|z|=0

The number of complex numbers z such that |z - i| = |z + i| = |z + 1| is

z is a complex number such that z^(2)+z+1=0 .Then the value of z^(30) is
