Thanks. These are the possible answers: 4(cos 270° + i sin 270°) 4(cos 90° + i sin 90°) 4(cos 0° + i sin 0°) 4(cos 180° + i sin 180°) So how do I find out which one of those is the answer if it is pi or 180 degrees? thanks again

\[z=\sqrt{4^{2}}=4\] \[\arg(z)= \pi \] \[4(\cos \pi+isin \pi)\]

So since your alternatives are in degrees and not radians you know it's 180 degrees.
