Point taken!

Thanks!

Now I know I failed the bonus question on my test

........ I mean what I said 4i

4i is a complex number....

if you you do not know what that is then you may as well not bother attempting this problem as you need an understanding of magnitude and complex numbers to solve it.

What....

And that site unfortunately only gives you the problem, but not a way to solve it

Please post this in Latex form.
