Express your answer in rectangular form both in EXACT value and approximate value. Round off approximate values to 5 decimal places. For each number, graph the roots in an Argand diagram showing the magnitude and angle of each of the roots. So there will be 2 Argand diagrams, one of no.1, the other separate diagram for no.2. 1. Find the nine roots of -256 – j256/3 . 2. Find all the roots of f (z) = 226 + 81/3 – j81
