text: a: 3-2i  b:5-i? a: 3-2i and b: 5-i  choices for answer:  a is greater b is greater they're equal cannot be determined d. complex numbers cannot be ordered as they have both size and direction  their moduli can be ranked |5 - i| > |3 - 2i|   and their directions can be given arg (3 - 2i) = arctan (-2/3) and arg (5 - i) = arctan (-1/5)   but you can draw no such ordering conclusions about these two complex numbers
