The norm of a vector $< a, b, c >$ $<a,b,c>$

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

Hence

$| | < 5, 3, - 3 > | | = \sqrt{5^{2} + 3^{2} + {(- 3)}^{2}} = \sqrt{43} = 6.56$ $|| < 5 , 3, -3 > ||=sqrt(5^2+3^2+(-3)^2)=sqrt43=6.56$

What is ||<5,3,−3>|| || < 5 , 3, -3 > || ?
