1.	If →a,→b&→c are 3 non-coplanar vectors and →p,→q&→r are vectors defined by →p→b×→a[→a→b→c],→q=→c×→a[→a→b→c] and →r=→a×→b[→a→b→c], and, then the value of (→a+→b).→p+(→b+→c).→q+(→c+→a).→r=
Answer» If $\to a, \to b & \to c$ are 3 non-coplanar vectors and $\to p, \to q & \to r$ are vectors defined by $\to p \frac{\to b \times \to a}{[\to a \to b \to c]}, \to q = \frac{\to c \times \to a}{[\to a \to b \to c]} a n d \to r = \frac{\to a \times \to b}{[\to a \to b \to c]}$ , and, then the value of $(\to a + \to b) . \to p + (\to b + \to c) . \to q + (\to c + \to a) . \to r =$
