`z/3 = 1` , then the value of ''z'' is

If |z+1+3i|=1 ,then the least value of |z| is sqrt(k)+m ,then evaluate sqrt(k-m)

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 the value of |z_1 + z_2+ z_3| is equal to

If |z-2-3i|=1 ,then the greatest value of |z| is sqrt(k)+m, then evaluate sqrt((k+m)+2)

If z=(-2)/(1+isqrt(3)) , then the value of "arg"(z) is a. pi b. pi/4 c. pi/3 d. (2pi)/3

For a complex number Z,|Z|=1 and "arg "(Z)=theta . If (Z)(Z^(2))(Z^(3))…(Z^(n))=1 , then the value of theta is

If | (z - i)/(z + 2i)| = 1, |z| = 5/2 then the value of |z + 3i|

If z + z^(-1)= 1 , then find the value of z^(100) + z^(-100) .

If |(z-25)/(z-1)| = 5 , the value of |z| is -
