If →a,→b and→care three vectors such that [→a →b →c]=1 – InterviewSolution

1.	If →a,→b and→care three vectors such that [→a →b →c]=1, then the value of [→a+→b →b+→c →c+→a]+[→a×→b →b×→c →c×→a]+[→a×(→b×→c) →b×(→c×→a) →c×(→a×→b)] is
Answer» If $\to a, \to b$ and $\to c$ are three vectors such that $[\to a \to b \to c] = 1$ , then the value of $[\to a + \to b \to b + \to c \to c + \to a] + [\to a \times \to b \to b \times \to c \to c \times \to a] + [\to a \times (\to b \times \to c) \to b \times (\to c \times \to a) \to c \times (\to a \times \to b)]$ is
