The correct answer is 102,345,678. The number 012,345,678 is considered an eight-digit number; any other rearrangement of the digits, or inserting a 9 in any position, gives a larger number.
Assuming no repeated digits, lowest first, 20; in any order 120; Allowing repeated digits: 216
Just arrange all numbers from highest to lowest, from left to right.So it would be:7532
014589, if leading 0s are acceptable. Otherwise, 104589.
four The lowest 5 digits prime number is 10007
If I understand the question correctly, the answer is 5678
It could be: 4760 = 1
Digits are from 1 to 9the sum of the 9 greatest digits is = 9+9+9+9+9+9+9+9+9 = 81the sum of the 9 lowest digits is = 1+1+1+1+1+1+1+1+1+1= 9and so :81 + 9 = 90
23
In descending order from highest to lowest
It is 1389.
Assuming that leading zeros are not permitted (that is the lowest ten digit number is 1 000 000 000), then there are 4 500 000 000 possible even numbers
When using significant digits, the product has only the number of significant digits as the lowest number in the factors. "20" has two significant digits and "310" has three. Therefore, the product has to have two significant digits. 310 × 20 = 6200 6200 already has two significant digits.
