# Unit vector?

## Homework Statement

Im given two vectors and im told to find theyre unit normal vector.

a x b

## The Attempt at a Solution

I used the cross product of the 2 vectors to find the normal vector, however, it came out to be i + j + k. My question is, is this already a unit vector or do i need to use the equation $$\hat{}n$$ = n/$$\left|n\right|$$?
