Homework Statement
I simply forget how to cross product if you have:
3(A x B)
Would it be 3A x B
or
A x B then take that result and multiply by 3?

SUMMARY
The discussion centers on the calculation of the cross product in the expression 3(A x B). The correct interpretation is that you first compute the cross product A x B and then multiply the result by 3, as confirmed by the property r(A x B) = (rA) x B = A x (rB) where r is a constant. This ensures that the scalar multiplication applies after the vector operation, maintaining the integrity of the cross product's properties.
