Your attachment concludes with "A = 0, Never True," which is self-evident from the fact that A = x^n where x and n are positive integers and n>2. So I don't understand why you bothered including the attachment with your post. However from the body of your post you seem to be asking whether there are any applications of Fermat's Last Theorem in the study of physics. I can't think of any. Most natural phenomena studied in classical physics involve continuous functions, whereas number theory problems such as Fermat's Last Theorem involve discrete integer values only. And while quantum mechanics involves discrete values of quanta, I'm not aware of any applications that involve higher order powers of discrete values. But I'll be the first to admit that I am not an expert in that area.
