If `[a xx b b xx c c xx a] lambda [a b c]^(2)` then `lambda` is equal to

If [[axxb,bxxc, c xxa]]=lambda[[a, b, c]]^(2) , then lambda is equal to

If a + 2b - c = 0 and a xx b + b xx c + c xx a = lambda (a xx b) , then the value of lambda is equal to a)5 b)4 c)2 d)-2

Let a,b,c be three vectors such that a ne 0 and a xx b = 2a xx c,|a| = |c| = 1, |b| = 4 and |b xx c| = sqrt(15) . If b - 2 c = lambda a, then lambda is equal ot

If a = I + j + k, b = i+ j, c = I and (a xx b) xx c = lambda a + mu b , then lambda + mu =

If vec a = i+j+k, vec b = i+j, vec c = i and (vec a xx vec b) xx vec c = lambda vec a + mu vec b , then lambda + mu

If a xx b = b xx c != 0 , then a + c =
