Question

I don't know how to put this answer in.

I got ik-ij-k^2+jk
-j-k-0+i
Answer i-j-k.
However, that answer is wrong. I tried putting it in <1,-1,-1> but it is also wrong. PLease help. Thanks!

Answer 1

`i * j = k \\ j * k = i \: and \: k * i = j \\ \\ j * i= - k \\ k * j = - i \\ i * k = - j \\ \\ (i - k) * (k - j) = \\ i * k - (i * j) - \\ (k * k) + (k * j) \\ note \\ \: i * i = j * j = k * k = 0`
