If bar(a)xxbar(b)=bar(c) and bar(b)xxbar(c)=bar(a), then

If bar(a)+bar(b)+bar(c), then

If bar(a)+bar(b)+bar(c)=bar(0) then bar(a)timesbar(b)=

If bar(c)=3bar(a)-2bar(b) , then prove that [bar(a)bar(b)bar(c)]=0 .

[bar(a)" "bar(b)+bar(c)" "bar(a)+bar(b)+bar(c)]=0

If bar(c) = 3 bar(a) - 2 bar(b) then prove that [(bar(a),bar(b),bar(c))] = 0

If [bar(a)+2bar(b)2bar(b)+bar(c)5bar(c)+bar(a)]=k[bar(a)bar(b)bar(c)]
