$| | < 4, - 3, - 8 > | | = \sqrt{89} \approx 9.434$ $|| < 4, -3, -8 > || = sqrt(89) ~~ 9.434$

Explanation:

In general we have:

$| | < a, b, c > | | = \sqrt{a^{2} + b^{2} + c^{2}}$ $|| < a, b, c > || = sqrt(a^2+b^2+c^2)$

So in our example:

$| | < 4, - 3, - 8 > | | = \sqrt{4^{2} + {(- 3)}^{2} + {(- 8)}^{2}}$ $|| < 4, -3, -8 > || = sqrt(4^2+(-3)^2+(-8)^2)$

$| | < 4, - 3, - 8 > | | = \sqrt{16 + 9 + 64}$ $color(white)(|| < 4, -3, -8 > ||) = sqrt(16+9+64)$

$| | < 4, - 3, - 8 > | | = \sqrt{89} \approx 9.434$ $color(white)(|| < 4, -3, -8 > ||) = sqrt(89) ~~ 9.434$
