The Power of Sudoku
(Eingestellt am 2. März 2021, 19:08 Uhr von 28degrees)
Whenever a caret (^) appears between two digits A and B, A^B appears directly after it. (Example: If a caret was between 3 and 4, then 3481 appears in that order, since 3^4=81) The equals signs are only to help show where A^B appears.
The digits on the marked diagonal sum to a perfect power.

For those that don't know, A^B means A multiplied by itself B times, so 3^4=3*3*3*3=81. A perfect power is a number of the form A^B, where B>1 (like a square, cube,...). These include 4,8,9,16,25,27,...
Lösungscode: Column 7

I believe 1 is usually not considered a perfect power - in other words, not only B>1, but A>1 as well.

Added definition of perfect power

I agree: "perfect power" is not a term that everybody knows, especially if English is not their first language. If you've bothered to explain A^B, you should definitely explain perfect power.
