Oh, dude, I mean, like, there are 4 digits in 1230, right? So you can totally make 4-digit numbers by using each of those digits once. That's like, 4 factorial, which is 24. So, you can totally write 24 different four-digit numbers using 1230 without repeating any digit. Easy peasy!
468, 486, 648, 684, 846, 864.
60: First digit can be any of 5, second any of 4 and last any of the remaining 3, so 5 x 4 x 3
There are 4*4*3*2*1 = 96 such numbers.
Factorial 4 ie 4 x 3 x 2 x 1 = 24
Most people prefer to write numbers using digits since this is far shorter than writing out the relevant words.

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