Question

Which complex number has an absolute value of 5?
A.–3 + 4i
B.2 + 3i
C.7 – 2i
D.9 + 4i

Answer 1

I just replied to get a notification when someone figures it out, but, idk, I would tink it's D, but I am really not sure.

Answer 2

absolute value of \(a+bi\) is \(\sqrt{a^2+b^2}\)

Answer 3

so for example the absolute value of \(-3+4i\) is
\[\sqrt{3^2+4^2}=\sqrt{9+16}=\sqrt{25}=5\]

Answer 4
