If `z 1 =5+3i` and ` z 2=2−3i` Find ` z 1+z 2` ​

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

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

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

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

If z_(1) = 4 -I and z_(2) = - 3 + 7i then find (i) z_(1) +z_(2) (ii) z_(1) -z_(2)

If z_(1) = 6 + 9i and z_(2) = 5 + 2i then find z_(1)/z_(2)

The complex numbers z 1 ​ ,z 2 ​ and z 3 ​ satisfying z 2 ​ −z 3 ​ z 1 ​ −z 3 ​ ​ = 2 1− 3 ​ i ​ are the vertices of a triangle which is

If Z_(1)=2 + 3i and z_(2) = -1 + 2i then find (i) z_(1) +z_(2) (ii) z_(1) -z_(2) (iii) z_(1).z_(2) (iv) z_(1)/z_(2)

If z_(1)=2 + 3i and z_(2)= 3+ i plot the number z_(1) + z_(2) . Also show that |z_(1)| + |z_(2)| gt |z_(1) + z_(2)|
