The number 2\[^{29}\] is interesting for the reason that it has nine digits in its base-10 form, and nine of the ten decimal digits are present.
Without calculating 2\[^{29}\], what's the missing digit?
The problem is trivial if you calculate the number, using a calculator or computer or by longhand multiplication.
