The largest number that can be made simply by rearranging the digits is 76210.
But this is nothing like the largest number: (6^7201) is bigger than 1 followed by 5603 zeros. (6^71)^20 is very much larger.
There are number that are larger still, such as 76210! = 1*2*3*...*76210
If the digits are only used once, each, the largest possible number would be 97,531
4^5827 which is approximately 1.597973114x103508
The smallest number is 5,789. The largest is 98,750. The difference is 92,961.
That depends a lot on how often you may repeat each digit, and what operations are allowed. If you just want to write a four-digit number, using each digit once, start by writing the largest digit on the left, then continue with the second-largest, etc.

write the largest number you can make using each of the digits 7,1,0,2, and 9 just once
Assign the digits from left to right, using the largest possible digit in each case. Don't forget to reserve an even digit for the last position.

87,542 is.
I guess the expected answer is 97210. Using factorials and exponents very much greater number can be obtained. For example, 97210 is a number with 6880 digits. And that is without using factorials.

The largest integer that can be formed by using the digits only once each and simply arranging them in some order is 8740. Otherwise, using exponents, much larger numbers are possible.
