(2) The answers are 49, 100, 9, 25/4.

]]>1) Let z and w be complex numbers satisfying |z| = 4 and |w| = 2. Then enter in the numbers |z+w|^2, |zw|^2, |z-w|^2, |z/w|^2 below, in the order listed above. If any of these cannot be uniquely determined from the information given, enter in a question mark.

2) Let z and w be complex numbers satisfying |z| = 5, |w| = 2, and z*(conjugate of w) = 6+8i. Then enter in the numbers |z+w|^2, |zw|^2, |z-w|^2, |z/w|^2 below, in the order listed above. If any of these cannot be uniquely determined from the information given, enter in a question mark.

Thanks in advance for the help,
