1.	If →a,→b,→c are three non coplanar vectors and a vector →r=(→r.→a)(→b×→c)+(→r.→b)(→c×→a)+(→r.→c)(→a×→b)λ, then the value of λ is:
Answer» If $\to a, \to b, \to c$ are three non coplanar vectors and a vector $\to r = \frac{(\to r . \to a) (\to b \times \to c) + (\to r . \to b) (\to c \times \to a) + (\to r . \to c) (\to a \times \to b)}{λ},$ then the value of $λ$ is:
