I came across this bit of math humor recently.
But I had not seen the math notation of an exponent written to the left of a number instead of the right. I tried to look it up in a search engine but got nothing.
However, I got the answer I was looking for by typing the question into GPT-4.1. It understood what I was referring to, and gave the correct answer.
Sadly, it got the middle part wrong. It's supposed to be 5 to the 10th power, not C(10,5). Oh well, AI is not perfect.
