To solve this problem, we need to identify the digits in the number that are the same distance away from the beginning of the number as they would be when arranged in decreasing order within the number.
Let's break down the given number, 57683421, into its individual digits: 5, 7, 6, 8, 3, 4, 2, and 1.
To determine if a digit satisfies the given condition, we need to find its position from the beginning of the number and compare it with its position when the number is arranged in decreasing order.
- Starting with the digit 5, its position from the beginning is 1, and its position when arranged in decreasing order is 8 (the last digit). Since these positions are not the same, 5 does not satisfy the condition.
- Moving on to the digit 7, its position from the beginning is 2, and its position when arranged in decreasing order is 7. Again, these positions are not the same, so 7 does not satisfy the condition.
- Continuing this process for the remaining digits, we find that none of them satisfy the condition individually.
Therefore, the answer is that there are more than three digits in the number 57683421 that do not satisfy the given condition.
Explanation:
- The given number is 57683421.
- We need to check each digit to see if it satisfies the condition.
- We start with the first digit, 5, and compare its position from the beginning (1) with its position when arranged in decreasing order (8).
- Since these positions are not the same, 5 does not satisfy the condition.
- We repeat this process for each digit in the number.
- After checking all the digits, we find that none of them satisfy the condition individually.
- Therefore, the answer is that there are more than three digits in the number that do not satisfy the given condition.
