this is a 2 part problem in which I completed the first part but need help with the second part.

The first question was to simplify these complex expressions. and match the ones that yield a similar answer (you can see from the photo)

The part I need help with is this question---

"Determine the modulus of each of the complex numbers in the matching pairs. List these moduli in order from smallest to largest. Use the letters of the matching pair in your listing"
