- joshuaissac 2y ago> 0 2^0 is a power of two and has all odd digits. Edit: If we include negative powers, there is also 2^-1, which is all odd except for the leading zero before the decimal point.

- SamBam 2y agoNice double-meaning.
- Someone 2y ago2^0 = 1 If we allow cheating, there are infinitely many. 2^(^2log(3.57)) equals 3.57, for example.
- 317070 2y ago2^0 and 2^{-1}. other positive integers will end on an even number, other negative integers will end with the numbers 25.
