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.

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.
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 :)
Oh, dude, there are 90 three-digit palindromic numbers. You see, a three-digit palindrome has the form "ABA," where A and B can be any digit from 1 to 9. So, you just multiply the possibilities for A and B, which is 9 choices each, and voilà, you get 9 x 10 = 90. Easy peasy, lemon squeezy!
Well, honey, there are 18 palindromic numbers between 10 and 200. Palindromic numbers are like your favorite guilty pleasure - they read the same forwards and backwards. So next time you see a palindromic number, give it a little wink and a nod for being symmetrical in all the right places.
Let the first and third digits be equal. Choose any other number as the second digit. 202, 919, etc.
