$\sqrt{254}$ $sqrt254$

Subtract corresponding components of the vectors.

$| | < - 15, 5, 2 > | |$ $||< -15,5,2 > ||$

To find its length, we will apply the distance formula from $(0, 0, 0)$ $(0,0,0)$ .

$| | < - 15, 5, 2 > | | = \sqrt{15^{2} + 5^{2} + 2^{2}} = \sqrt{254}$ $||< -15,5,2 > ||=sqrt(15^2+5^2+2^2)=sqrt254$

What is ||<−9,3,3>−<6,−2,1>|||| <-9, 3, 3 > - < 6, -2, 1 > ||?
