In the identical direction. keep the components' sign configuration (+ - +) constant.

For any vector u, the unit vetor in the direction of u is $\frac{1}{\left|u\right|}u$, where $\left|u\right|=\sqrt{}$(sum of the squares of the magnitudes of the components of u).

Here. it is $\frac{1}{9}(8i-j+4k)$
