There are two possible digits for the first and last digit, and two possible digits for the centre digit, making 2 × 2 = 4 possible 3 digit palindromes from the set {1, 2}, namely the set {111, 121, 212, 222}.

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.


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).


How many different three-digit palindromes can you make using only the digits 1 and 2?

111, 121, 212, 222


Can 100 different digits make 100 multiplied by 100 equal 10000 different three digits palindromes?

Yes. But that is true only if the 100 digits do not include 0. Or, if 0 is included, then you consider "0n0" to be a three digit number. Most people would consider is to be a 2-digit number.


What is the maximum number of different three digit palindromes you can make using any digit?

There are 10 digits, but for a three digit number the first number cannot be a 0. Thus: there is a choice of 9 digits for the first (and last digit which must be the same), with 10 choices of digit for the second (middle) digit, making 9 × 10 = 90 such palindromic numbers.

How many palindromes are from 0 to 1000?

There are 199 palindromic numbers between 0 and 1000. These include single-digit numbers (0 to 9), two-digit numbers (e.g., 11, 22, ... 99), and three-digit numbers (e.g., 101, 111, ... 999). Each of these categories contributes to the total, with the three-digit palindromes being in the form of ABA, where A and B are digits.


What is the three digit Number in a palindrome?

A three-digit palindrome is a number that reads the same forwards and backwards, typically in the format "ABA," where A and B are digits. For example, 121 and 484 are both three-digit palindromes. The first and last digits (A) must be the same, while the middle digit (B) can be any digit from 0 to 9. Thus, valid examples include 101, 222, and 999.
