Without repeating digits (not digets!) and without leading 0s, 600 of them.
They can. And if you include repeating 0s and repeating 9s, then all rational numbers can be written with infinitely long repeating digits.

18, if leading 0s are disallowed.
Using only arrangements of the given digits: without repeating digits, 15. with repetition, 39. The answer does not include numbers such as 2^3 = 8 or 3^(2+1) = 27
