1001 is the smallest 4 digit palindromic number.
90
there are 10 palindromic numbers between 9000 and 10000 9009,9119,9229,9339,9449,9559,9669,9779,9889,9999!!!

a 8-digits palindromic number is a number consisting of a 4-digits number written and then written backward, i.e. 1234 4321 so there are as many palindromic 8-digits numbers as 4-digits numbers so from 1000 to 9999, so there are 8999 palindromic 8 digits number (I assumed that 00011000 is not to be considered as a valid 8 digit number)
HENS
Assuming leading zeros don't count: 1001

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.
