[" If "quad d=lambda(a times b)+mu(b times c)+v(c times a)" and "],[[abc]=(1)/(8)," then "lambda+mu+v" is equal to "]

If vecd = gamma(veca xx vecb) + mu(vecb xx vecc) + v(vecc xx veca) and [veca vecb vecc]=1/8 , then lambda = mu + v is equal to:

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

If (a - lambda b) . (b - 2c) xx (c + 3a) = 0 then lambda =

vec d = lambda (vec a xxvec b) + mu (vec b xxvec c) + nu (vec c xxvec a) and [vec aquad vec bquad vec c] = (1) / (8), then lambda + mu + nu =

If a, b, c, d lie in the same plane then (a times b) times (c times d) is equal to
