1.	Let →a=2^i+^j−2^k and →b=^i+^j. If →c is a vector such that →a⋅→c=\|→c\| and \|→c−→a\|=2√2 and the angle between (→a×→b) and →c is 300, then \|(→a×→b)×→c\| is equal to
Answer» Let $\to a = 2^i +^j - 2^k$ and $\to b =^i +^j .$ If $\to c$ is a vector such that $\to a \cdot \to c = \| \to c \| and \| \to c - \to a \| = 2 \sqrt{2}$ and the angle between $(\to a \times \to b)$ and $\to c$ is $30^{0}$ , then $\| (\to a \times \to b) \times \to c \|$ is equal to
