Are there more 11 digit or 12 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.
What is the number when multiplied by itself is equal to the square root of that number with reverse integers?
I think that the question is asking for palindromic square numbers, that is numbers that read the same backwards as forwards. 11² = 121 so √121 = 11 22² = 484 so √484 = 22 26² = 676 so √676 = 26 and there are many more numbers that produce this pattern :- 101²= 10201 121² = 14641 . . . and so on.
Do the product of two palindromes equal another palindrome?
Not as a rule. It does occur sometimes, as in 11x22=242. But more often than not, the product will not be palindromic.
Are there more composite or prime numbers?
there are more composite numbers the prime becuz more things can be divided into
Are there more deficient numbers than abundant and perfect numbers?
There are more deficient numbers.
