I don't know how to make the vector arrow on top of the letter so I just underlined the vectors. Also I don't know how to make the square root symbol so I just type sqrt for it.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

Which points in the same direction as V = (-sqrt2, sqrt3, sqrt5)

a) 1/10 V

b) sqrt10/10 V

c) sqrt10 V

d) sqrt 10 V

2. Relevant equations

3. The attempt at a solution

I am not sure where to start other than calulating the sqrt of 2,3, and 5. My best guess would be c but I need to know why if that is correct or some help figuring it out.

Please help,

Thanks,

Marion
