$\sqrt{202} \approx 14.21$ $sqrt202~~14.21$ .

Let, $\to x = (- 3, 5, 1), and, \to v = (4, - 7, 4)$ $vecx=(-3,5,1), and, vecv=(4,-7,4)$ .

$:. vecu-vecv=(-3-4,5-(-7),1-4)=(-7,12,-3)$ ,

$:. ||vecu-vecv||=sqrt{(-7)^2+12^2+(-3)^2}$ ,

$=sqrt(49+144+9)$ .

$rArr ||vecu-vecv||=sqrt202~~14.21$ .

What is || <-3, 5, 1> - < 4 , -7, 4 > ||||<−3,5,1>−<4,−7,4>|||| <-3, 5, 1> - < 4 , -7, 4 > ||?
