`Z=-5+4i `then `Z^4 +9Z^3 +35Z^2 – Z + 4 =`

If z=3-4i then z^4-3z^3+3z^2+99z-95 is equal to

If z= -3 + sqrt2i , then prove that z^(4) + 5z^(3) + 8z^(2) + 7z + 4 is equal to -29

If z = i(i + sqrt(2)) , then value of z^(4) + 4z^(3) + 6z^(2) + 4z is

If z = 3-4i , then z^4-3z^3+3z^2+99z-95 is

If z=3-4i then z^(4)-3z^(3)+3z^(2)+99z-95 is equal to

If z=4+i sqrt(7) then the value of Z^(3)-4Z^(2)-9z+91 equal

If z_(1)= 4-3i and z_(2) = 3 + 9i " 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 + 4i , Z_2 = 12 - 5i , prove that |z_1+z_2|<|z_1-z_2|

If z_1 = 3 + 4i , z_2 = 5 - 12i and z_3 = 6 + 8i , find |z_1|, |z_2|,|z_3|, |z_1 + z_2|,|z_2 - z_3|, and |z_1 + z_3| .
