How many different palindromes are there with 6 digits?
For there to be palindromes, each digit must be replicated. Therefore there are at most three distinct digits.If there are 3 pairs of different digits, then there are 6 palindromes. If there can be more duplicate digits, then there are 27 palindromes.
How many 4-digit palindromes are there?
There are 90 four-digit palindromes
How many four digit palindromes are there?
There is 90 four digit palindromes.
Can 100 different digits make 10010010000 different three digits palindromes why?
No, 100 different digits cannot make 10,010,010,000 different three-digit palindromes. A three-digit palindrome has the form "ABA," where A is the first and last digit, and B is the middle digit. Since A can be any digit from 1 to 9 (for the first digit) and B can be any digit from 0 to 9, there are only 9 options for A and 10 options for B, resulting in a total of 90 unique three-digit palindromes (9 x 10 = 90).

What is the smallest digits palindrome that is the sum of two 3 digit palindromes?
The smallest digit palindrome that is the sum of two 3-digit palindromes is 121. This is achieved by adding the two 3-digit palindromes 101 and 20, both of which are palindromic. Therefore, 101 + 101 = 202, but if we consider a valid case with two different palindromes, we can use 111 and 110, which gives us 221, the next smallest palindrome. However, the smallest individual palindrome formed by the sum of any two 3-digit palindromes remains 121.
How many palindromes have 6 digits?

How many 3-digit odd palindromes are divisible by 5?
There are 10 3-digit odd palindromes that are divisible by five.
What are examples of 3 digit numbers that transform into palindromes?
Any, and every, number can be transformed into a palindrome.
How many 5 digit palindromes are there?
900 This explains it. A positive integer is a palindrome if it reads the same forward and backwards such as 1287821 and 4554. Determine the number of 5-digit positive integers which are NOT palindromes. We start by counting the total number of 5 digit positive integers. The first digit is between 1 and 9, so we have 9 choices. Each of the other 4 digits can be anything at all (10 choices for each). This gives us 9(10)4 = 90000 five-digit positive integers. Now we need to count the number of 5 digit palindromes. Again, we have 9 choices for the first digit and 10 choices for each of the next two. The tens and units digits however are fixed by our choices so far. Therefore, there are only 900 five-digit palindromes. Therefore, the total number of five-digit positive integers which are not palindromes is 90000-900 = 89100.
Are there more 10-digit or 11-digit palindromic numbers?
