if `|z-2+3i|=2` and `|z+1+3i|=1` then evaluate `|z-4|`

If |z+2i|<=1 and z_(1)=6-3i then the maximum value of |iz+z_(1)-4| is equal to

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

If z_1 = 3i and z_2 = -1 -i , find the value of arg z_1/z_2 .

For all complex numbers z_(1),z_(2) satisfying |z_(1)|=12 and |z_(2)-3-4i|=5, find the minimum value of |z_(1)-z_(2)|

if z_(1) = 3i and z_(2) =1 + 2i , then find z_(1)z_(2) -z_(1)

if z_(1) =2+3i and z_(2) = 1+i then find, |z_(1)+z_(2)|

If z_(1) = 2+ 3i and z_(2) = 5-3i " then " z_(1)z_(2) is

If z_(1)= 4-3i and z_(2) = 3 + 9i " then " z_(1) -z_(2) is

if z_(1) = 3-i and z_(2) = -3 +i, then find Re ((z_(1)z_(2))/(barz_(1)))
