5 Digit Number (Posted on 2003-08-20) Difficulty: 3 of 5
I am thinking of a 5 digit number that when tripled is a perfect square.

Also, when the 5 digit number is split, the first number is double the second one. What is the five digit number?

(Splitting the 5 digit number into two numbers means 12345 into 1 and 2345 or 123 and 45.)

The extended version of this problem has already been discussed from base 11 to base 36 inclusively in "5 Digit Number II" (http://perplexus.info/show.php?pid=7073&cid=45640) four months before.
