To normalize a vector we divide each element by the length of the vector.

The resulting vector is $(7/sqrt54i-1/sqrt54j+2/sqrt54k)$

Find the length of the vector:

$l=sqrt(7^2+(-1)^2+2^2)=sqrt54$

Divide each element of the original vector by $sqrt54$ .

How do you normalize (7 i -j +2k)(7 i -j +2k)?
