I cheated, and used bc, the unix utility.
These three maneuvers (the correct answer, the agency shown by cheating, and the crystallized intelligence of unix) handily demonstrate both my own intelligence, and that of my species.
The LLMs aren't in the same category of being, yet. It's not clear they ever will be; while I think silicon is a viable substrate for intelligent agents, it still strikes me as doubtful they'll be any more descended from the current machine learning systems as they are from Symbolics Lisp.
