Asked by SaraH
I'm kinda confused with this problem. We're working with imaginary numbers. Is my work correct?
Compare the quantity in Column A with the quantity in Column B.
Column A = |3 - 2i|
Column B = |5 - i|
···································
My work
Column A
3 + 2 = 5
Column B
5 + 1= 6
Answer: Column B is greater.

Clearly you have not read the section on complex numbers
|3-2i| = √(3^2+2^2) = √13
|5-i| = √(5^2+1^2) = √26
|3-2i| = √(3^2+2^2) = √13
|5-i| = √(5^2+1^2) = √26

I actually did, but my textbook and study guide didn't have any practice questions like this one. Thanks for your help anyways. Have a nice day!

pardon my skepticism. Any introduction to complex numbers explains how to find their magnitude.
