`z(5z^(2)-80)` को `5z(z+4)` से भाग दीजिए।

Divide z(5z^(2)-80) by 5z(z+4)

Divide z (5z^2-80) by 5z(z+4)

Divide z(5z^2 – 80) by 5z(z + 4)

Work out the division: z(5z^(2)-80)-:5z(z+4)

Work out the following divisions: z(5z^2-80) -: 5z(z+4)

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

Let z_(1), z_(2), z_(3) be the roots of iz^(3) + 5z^(2) - z + 5i = 0 , then |z_(1)| + |z_(2)| + |z_(3)| = _____________.

If z_(1) = 1 - 3i, z_(2) = -4i and z_(3) = 5, show that (z_(1) + z_(2)) + z_(3) = z_(1) + (z_(2) + z_(3))
