Three non-zero non-collinear vectors bar(a), bar(b), bar(c) are such that bar(a)+3bar(b) is collinear with bar(c) , while bar(c) is 3bar(b)+2bar(c) collinear with bar(a) .Then bar(a)+3bar(b)+2bar(c)=

If |bar(a)|=1,|bar(b)|=2 , (bar(a),bar(b))=(2 pi)/(3) then |(bar(a)+3bar(b))times(3bar(a)-bar(b))|^(7)= ...
