I thought that perhaps y’all might like a bit of a brain teaser. I don’t know how many more of these little teasers there will be, or if there will be any more at all, but I created a category specially for them, I know, I’m a risk taker.
What is the first square number that contains one and only ONE zero?
In case you were wondering, no, this isn’t a trick question. The reason I write one in capital letters is because I want to stress that the answer is not 100, because that has TWO zero’s.
This one isn’t too hard, and I’m sure that most people reading this (yes, all both of you) would be capable of writing a little program to work it out for you. However, try figuring it out yourself first, using a calculator is fine but don’t just go through the numbers squaring them until you find a zero.
If you find the answer without too much bother or if someone has already posted the answer in a comment and you accidentally read it, try finding the next, and the one after that.
