What is the least three-digit palindrome that is a square number?
Ben / Parent for a 3rd grader
Hi Ben,
Rather than examining three digit numbers and looking for squares, consider one and two digit numbers, square them and look for the first time you get a three digit palindrome.

8 squared is a two digit number
9 squared is a two digit number
10 squared is three digits but not a palindrome
