i think you might be right
OpenStudy (anonymous):
I mean I look at it and it doesn't have any negative signs in it so that's the only one that fits.
jimthompson5910 (jim_thompson5910):
2+7i is the original number it is NOT the conjugate (so it's NOT the answer)

original: a+bi conjugate: a-bi
OpenStudy (anonymous):
Oh so it would be 2-7i?
