How would I solve (B/B) • B if given vector B?

Question

So I am given that vector B is in quadrant 1 and the magnitude of vector B is 6.9 and the angle of vector B is 53.0. So what would (B/B) • B = ?

Answer 1

I assume you meant to ask for

(B / |B|) • B = ?

(B / |B|) • B = (1 / |B|) (B•B) = (1 / |B|) |B|² = |B| = 6.9

Note Kevin's comment. The angle does not matter in this problem.
