## Homework Statement

If \parallel u\=2, \parallel v\=√3, and u*v=1, find \parallel u+v\.

## Homework Equations

None.

## The Attempt at a Solution

(u+v)(u+v)=(\parallel u\)

^{2}+2uv+(\parallel v\)

^{2}=4+3+2=9

\parallel u+v\\=3

So the answer I got is 3. Am I right? If not, then please correct me.
