Theorem
The following pattern holds:
\(\ds 3^2\) | \(=\) | \(\ds 9\) | ||||||||||||
\(\ds 23^2\) | \(=\) | \(\ds 529\) | ||||||||||||
\(\ds 233^2\) | \(=\) | \(\ds 54 \, 289\) | ||||||||||||
\(\ds 2333^2\) | \(=\) | \(\ds 5 \, 442 \, 889\) | ||||||||||||
\(\ds 23333^2\) | \(=\) | \(\ds 544 \, 428 \, 889\) |
and so on.
