Find →A×→B, if →A=2^i−^j+3^k and →B=−2^i+3^j+4^k
Let →a and →b are vectors such that |→a+→b|=√29 and →a×(2^i+3^j+4^k)=(2^i+3^j+4^k)×→b then (→a+→b).(−7^i+2^j+3^k)=
If →a and →b are vectors such that |→a+→b|=√29 and →a×(2^i+3^j+4^k)=(2^i+3^j+4^k)×→b, then a possible value of (→a+→b).(−7^i+2^j+3^k) is
