Let z0 be the complex number satisfying |z − 5| ≤ 3 and having maximum positive argument, then the value of 34 × |5z0 − 125iz0 + 16|2 is equal to:

If z is a complex number satisfying the relation |z + 1| = z + 2(1 + i), then z is:

z1, z2 and z3 are the vertices of an equilateral triangle inscribed in the circle |z| = 2. If z1 = 1 + i√3, then the values of z2 and z3 are:

The value of the expression x3 - 5x2 + 33x - 19, where x - 2 = 5i, is equal to:
