Compare column A (3-2i) to column B (5-i)?

Question

Column A: 3-2i Column B: 5-i

Notice I used the letter i.
The choices for the answer are:

Quantity in column A is greater
Quantity in column B is greater
The two quantities are equal
Cannot be determined based on the provided information

Answer 1

What is this about? Are they complex numbers, with i representing the ordered pair (0, 1). And does quantity mean what we usually call modulus? (or sometimes, magnitude?)

That's the only meaning I can think of, and if it's right, the modulus of the first one is sqrt(3^2+(-2)^2) and the second is sqrt(5^2 + (-1)^2), and you can take it from there.

Answer 2

You want to compare 3-2i and 5-i, right?

They're both complex numbers which are not ordered: you canno say > or < but you can say = if they are the same.

Since they are complex and not equal that's all that you can say.
