Special Numbers (Posted on 2004-04-03) Difficulty: 2 of 5
There exists a number oddity with 3 different 4-digit numbers. One is 9801, where (98 + 01)^2 = 9801. It also works with 3025: (30+25)^2 = 3025.
What is the other number?
What is the smallest 6-digit number that would work?
(in other words, in a 6-digit number abcdef: abcdef=(abc+def)^2)

You can edit your previous posts.  Instead of posting 6 times on the same thing, go back to one of your posts, and at the bottom you will see a link that says "edit your post" or something.

I tent to give up on square root signs, or superscripts for powers.  I just say sqrt(x) or x^2 in those cases.  It's messy, but not as messy as garbled text.

hope this helps!
