Well, what's eight to the 1 3rd power? Eight to the 1 3rd power is going to be equal to two, and so eight to the negative 1 3rd power is 1 1.5. Actually, let me just do that step by step. So this is going to be equal to 2 3rds times, we could do it this way, one over eight to the 1 3rd power. And so this is just one over two, 2 3rds times 1 1.5. Well, that's just going to be equal to 1 3rd. And we're done.
