1. Find the modulus and argument of (1 + i)^6.
2. Find the roots of the equation z^3 - 2z^2 + (2 + 2i)z - (1 + 3i) = 0.
3. Find the complex number w such that w^4 = (1 + i)^4 and w has a negative real part.
4. Find all values of z such that |z - 2i| = 3.
5. If z = a + bi and w = 3 - 4i, find the values of a and b that satisfy the equation zw + 5 = 0.
