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.

4 x 3 x 2 ie 24
96425 Larger numbers can be made by cascading the powers, but not on here because the notation won't take it.
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

There are three main types of decimal numbers:Terminating: these come to an end after a finite number of digits. These are the number 0 and also numbers such that their rational representation in the simplest form has a denominator whose only prime factors are 2 and 5.Repeating: these have a string of digits which repeats without end. The string may start afetr a finite number of non-repeating digits. For example, 2.1346515235235235... has the 3-digit string "235" repeating, but not straight away. These are numbers whose rational representation in the simplest form has a denominator which has a prime factor other than 2 or 5.Non-terminating and non-repeating: these have an endless number of digits with no repeating strings. These digits may be random or may contain patterns, such as 5.12122122212222.... but there cannot be a repeating string. These are irrational numbers.
