11. NCERT | Digital Roots | Intext | Pg.130 | Q6

I’m made of digits, each tiniest and odd,

No shared ground with root #\(1\)—how odd!

My digits count, their sum, my root—

All point to one bold number’s pursuit—

The largest odd single-digit I proudly claim.

What’s my number? What’s my name?

\(999,999,999\) - repunit number
\(999,999,999\) - largest odd number
\(111,111,111\) - repunit number
\(9\) - largest odd number
