Um... REALLY? If you can only use each number once then it's 9521.
Arranging them in the order 9521 produces the largest number. Using operands, using the exponential function (if available) would create the largest number. [(2 ^5)^9]^1= 35184372088832
write the largest number you can make using each of the digits 7,1,0,2, and 9 just once
There is no largest number. If somebody ever hands you a number and tells you that it is the largest, bring it to me. I will add ' 1 ' to it and make a larger one.
If the digits are only used once, each, the largest possible number would be 97,531
That depends on what base you are using. It could be 1
the answer would depend on what you are talking about. The largest number of those is 8. Or if you want to make the largest number it would be 84310
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 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
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.
