Dude. How do you Uncross a cross product?

Homework Statement

If I have $\vec{v}=\vec{\omega}\times\vec{r}$ how do I solve for omega? How do I "cross divide"?

Scalar operations are easier, I know. But how do you do this vectorially?

Does that help?

Specifically,

2) cross division /x
A /x B = (A x B) / B^2 or
A /x B = A^2 / (A x B)
