Question: Reduction of a complex zero vector

I have a vector, it is a zero vector apparently. I don't know what opperation lead to it being a zero vector. Any time I try to reduce this thing, I mess it up. I can't reduce it manually.







The simplify command will reduce this bugger no problem. The moment I try rationalizing the denominator or anything like that I end up buggering the whole thing up. Maybe I should do a distance on two of the ordinates independently first. Anyway, I don't know what's up. 

Please Wait...
