∙ 14y agothe squares of 10 though 22 are all three digit numbers under 500.
though none of the sums of their digits total an even multiple of 15.

Single digit primes are 2, 3, 5, 7 Single digit squares are 1, 4, 9 Neither prime nor square are 0, 6, 8 None of that makes a difference if we can't figure out what a "grerate" is. I'll guess you want to know the greatest possible number given those conditions. That would be 985.
Every square of a 4 digit number has more than four digits.
81...........
1111Improved Answer:-It is 1008 because 1008/9 = 112Any number is divisable by 9 if the sum of its digits equals 9.

The number is 81.
The square root of 55 is an irrational number, meaning it never ends and doesn't have a repeating digit pattern, so it has an infinite number of digits.
