1. Problem Description

The problem asks us to calculate the Euclidean norm of vector vv for four different cases:
a) v=(4,3)v = (4, -3)
b) v=(1,1,3)v = (1, -1, 3)
c) v=(2,0,3,1)v = (2, 0, 3, -1)
d) v=(1,1,1,3,6)v = (-1, 1, 1, 3, 6)

2. Solution Steps

The Euclidean norm of a vector v=(v1,v2,...,vn)v = (v_1, v_2, ..., v_n) is defined as:
v=v12+v22+...+vn2||v|| = \sqrt{v_1^2 + v_2^2 + ... + v_n^2}
a) v=(4,3)v = (4, -3)
v=42+(3)2=16+9=25=5||v|| = \sqrt{4^2 + (-3)^2} = \sqrt{16 + 9} = \sqrt{25} = 5
b) v=(1,1,3)v = (1, -1, 3)
v=12+(1)2+32=1+1+9=11||v|| = \sqrt{1^2 + (-1)^2 + 3^2} = \sqrt{1 + 1 + 9} = \sqrt{11}
c) v=(2,0,3,1)v = (2, 0, 3, -1)
v=22+02+32+(1)2=4+0+9+1=14||v|| = \sqrt{2^2 + 0^2 + 3^2 + (-1)^2} = \sqrt{4 + 0 + 9 + 1} = \sqrt{14}
d) v=(1,1,1,3,6)v = (-1, 1, 1, 3, 6)
v=(1)2+12+12+32+62=1+1+1+9+36=48=163=43||v|| = \sqrt{(-1)^2 + 1^2 + 1^2 + 3^2 + 6^2} = \sqrt{1 + 1 + 1 + 9 + 36} = \sqrt{48} = \sqrt{16 \cdot 3} = 4\sqrt{3}

3. Final Answer

a) v=5||v|| = 5
b) v=11||v|| = \sqrt{11}
c) v=14||v|| = \sqrt{14}
d) v=43||v|| = 4\sqrt{3}
