the other answer options I have are 6(cos 7pi/4 + i sin 7pi/4) sqrt6(cos 7pi/4  i sin 7pi/4) and sqrt6(cos 7pi/4 + i sin 7pi/4) I thought I worked it out correctly, guess not.

it helps to know what quadrant you are in so you can find the angle more easily \(\frac{\pi}{4}\) would put you in quadrant 1 but you are in quadrant 4
