89 does not have any other number - palindromic or otherwise.
As 20569.8 is not palindromic, any number that is like it must contain that property and similarly be non-palindromic, so no.
No, 11 is the only palindromic prime with an even number of digits.
No, the number 2 is not considered palindromic in the context of multiple digits. A palindromic number reads the same forwards and backwards. For single-digit numbers like 2, it remains the same, but palindromic typically refers to numbers with at least two digits, such as 121 or 1331. However, in a broader sense, any single-digit number can be seen as trivially palindromic.

Palindromic numbers occur with varying frequency depending on the range considered. In any given set of numbers, the likelihood of encountering a palindromic number increases as the range expands. For example, among one-digit numbers, all are palindromic, while in larger ranges, the density decreases but still remains significant. Overall, palindromic numbers are not rare and can be found throughout the number system.
Other than the fact that much of mathematics is about patterns, NO.
To be a 3 digit palindromic number, it must be of the form aba.I assume that a 3 digit number must be at least 100 (so that 020 for example does not count as a 3 digit number):a can be any of the nine digits 1-9;for each of these b can be any of the ten digits 0-9Thus there are 9 x 10 = 90 three digit palindromic numbers.
A three-digit palindromic number is a number that reads the same forwards and backwards, consisting of three digits. These numbers take the form ( aba ), where ( a ) is any digit from 1 to 9 (to ensure it's a three-digit number), and ( b ) is any digit from 0 to 9. Examples include 101, 121, 131, and so on, up to 999. There are a total of 90 three-digit palindromic numbers.
There are more 12-digit palindromic numbers than 11-digit palindromic numbers. This is because the number of possible 12-digit palindromic numbers is greater than the number of possible 11-digit palindromic numbers. In general, the number of palindromic numbers of length n is 9 * 10^((n-1)/2), so for 11-digit palindromic numbers, there are 9 * 10^5 = 900,000 possibilities, while for 12-digit palindromic numbers, there are 9 * 10^6 = 9,000,000 possibilities.
Because any 3 digit number ending in 4, 5 or 6 is composite.
20th of march 2002, 20th of Jan 2002, 20th of feb 2002, 20th of April 2002, 20th of may 2002. Basically in 2002 the palindromic dates are 20th,any date, and 2002 .Same thing with 2003 (30th, any month, 2003). Hope this helps :)
