1.	If [→a+→b →b+→c →c+→a]=λ1[→a →b →c] and [→a×→b →b×→c →c×→a]=[→a →b →c]λ2 then λ1+λ23 is (where →a,→b,→c are non zero and non coplanar vectors)
Answer» If $[\to a + \to b \to b + \to c \to c + \to a] = λ_{1} [\to a \to b \to c]$ and $[\to a \times \to b \to b \times \to c \to c \times \to a] = [\to a \to b \to c]^{λ_{2}}$ then $\frac{λ_{1} + λ_{2}}{3}$ is (where $\to a, \to b, \to c$ are non zero and non coplanar vectors)
