Yes, because the sequence of digits is the same when read either forward or backward. (The spacing between the digits is irrelevant.)
Yes.
No, 303 is divisible by 3, 303 = 101 x 3; and also = 303 x 1. Since it has factors in addition to 1 and itself it is not prime.
A palindromic cube is a number that is both a cube of an integer and a palindrome, meaning it reads the same forwards and backwards. For example, ( 1^3 = 1 ) and ( 2^3 = 8 ) are not palindromic, but ( 3^3 = 27 ) is also not palindromic. However, ( 4^3 = 64 ) is likewise not palindromic. An example of a palindromic cube is ( 5^3 = 125 ), as it reads the same in reverse form, although it is important to note that actual palindromic cubes in their entirety are rare.
what ever number followed by 303 zero's. Ex: 1 (and 303 0's.)
There are the same number: any twelve digit palindrome is just an eleven digit palindrome with its central digit repeated. In general, if we are considering numbers of n digits: For even values of n, the number of palindromes is 9 x 10n/2 - 1 For odd values of n, the number of palindromes is 9 x 10(n-1)/2
Yes.
The number 303 can be factored into: 303 = 3 * 101. Thus, 303 is divisible by 1, 3, 101, and 303.

An Centrillion is a 1 followed by 303 zeros. Not quite. In the U.S., a centrillin is 1, then 303 zeroes. However, In UK and Britain, it is a 1 followed by 600 0's

That would be 26 . . . its square is 676.There are two smaller palindromic squares . . . 121 and 484 ... but they're the squares of11 and 22 respectively, which are palindromic, so they flunk the question's specifications.

1. 1991 is the only number I think.
I suppose you meant palindrome. Palindromic number in maths means number which stays same if we reverse it. e.g. 11, 151, 6886 are palindromic, but 1211, 100 or 15 aren't. 1, 2, 3, 4, 5, 6, 7, 8 and 9 are considered palindromic too.
