Question

Find the length of the vector V = || 2 3 1 ||- Ensure that you use at least 4 decimal place accuracy or exact values when entering your answer.

Answer 1

Answer:
`√(14)`

Explanation:

The given notation is not clear enough, but I will asume that the question is: "Wich is the vector lenght of the vector
`(2,3,1)` in a 3 dimensional euclidean space"

Vector lenght of a vector
`(a,b,c)` is given by the next formula:

║
`(a,b,c)`║=
`√(a^2+b^2+c^2)`

In this case we have a=2, b=3 and c=1. We should substitute these values in the formula given before to obtain:

║
`(2,3,1)`║=
`√(2^2+3^2+1^2)=√(14)=3.74165`

Wich is the answer to the problem.
