[a*p b*q c*r] + [a*q b*r c*p] + [a*r b*p c*q] =
i think sum info may have been given abt the nature of a,b,c and abt p,q,r........lik not zero vectors,not parallel vectors.......etc..........
if not consider the special case,like a=0 and the answer will be ZERO
if the answer is mentioned sumthing else,plz do mention me.......
Cheers!
