(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

pXq-r

2. Relevant equations

3. The attempt at a solution

In order to evaluate this expression, I must first evaluateq-rand then perform the cross product, right? I'm trying to think about X as an operator, like del, that operates on the things that appear after it. Is this correct?

Thanks.
