Find the greatest and the least value of `|z_1+z_2|` if`z_1=24+7ia n d|z_2|=6.`

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

Find the greatest and least value of |z_(1)+z_(2)|=" if " z_(1)=24 + 7i and |z_(2)|=7

|z +3| <= 3 , then the greatest and least value of |z | are

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

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

If |z+4|lt=3 then find the greatest and least values of |z+1|dot

Statement-1 : IF |z+1/z| =a , where z is a complex number and a is a real number, the least and greatest values of |z| are (sqrt(a^(2)+4-a))/2 and (sqrt(a^(2)+ 4)+a)/2 and Statement -2 : For a equal ot zero the greatest and the least values of |z| are equal .

If |z-4/z|=2 then the greatest value of |z| is:

Let z be a complex number satisfying 1/2 le |z| le 4 , then sum of greatest and least values of |z+1/z| is :

For any two complex numbers z_1\ a n d\ z_2 and any two real numbers a ,\ b find the value of |a z_1-b z_2|^2+|a z_2+b z_1|^2dot
