I've encountered the same issue twice with my power-reducing identities where I am supposed to cancel a denominator and move the fraction to the other term. I'm not sure how to do this however since those are opposite operations right? Attached are the two problems, I need to prove the identities next to the circled numbers.

Wait, I just realized. In the case of #40, maybe I need to pull the 1/2 out as a fraction and instead multiply it onto the other term. I can do that since multiplication can be done in any order right?
