If you know that Z = 4 + 2i and X = -23-6i Perform the indicated operation and write your answer in polar form. 1. Z+X 2. Z-X 3. Z.X 4. Z/X 137 Q2 Put the complex number Z = 2e in the "Cartesian" form Z = a + bi where a, b E R. Q3 Put the complex number Z = 18 +26i in the "polar" form Z = re where r. 0 ER and both r and 0 are positive. Q4 Find a cube root of the number Z = 18 +26i and put this cube root in the "Cartesian" form Z = a + bi where a, b E R. (Use a calculator and get an exact value.)
