Evaluate [ hat i hat j hat k][ hat i hat...

Evaluate `[ hat i hat j hat k][ hat i hat k hat j]`

Text Solution

Verified by Experts

`[ hat i hat j hat k][ hat i hat k hat j]`
`hat i. (hat j times hat k) (hat i.(hat k times hat j))`
`hat i .hat i).(hat i.(-hat i))`
`1(-1)=-1`

Hence, the value of `[ hat i hat j hat k][ hat i hat k hat j]=-1`
