A digital arrangement (Posted on 2005-06-30) Difficulty: 3 of 5
Without using any arithmetical symbols (+, -, *, /, or similar; other math symbols; decimal comma or periods; letters; even parentheses) or, in short, anything but the digits, build a number with the digits 1, 3, 5, 7 and 9, that is equal to a number built with the digits 2, 4, 6 and 8 (each digit used once and only once).

Note: This is not a trick. It was extracted from a book edited by Angela Dunn, a mathematician who gathered problems that appeared in many scientific periodical revues!

(In reply to Avoiding the big digit trick by owl)

Very good, owl, I´m satisfied. Since it´s not my solution, I think we could conclude that possibly there are many more solutions.

The only "tools" that we have is, indeed, superscript (to indicate power) and subscript (to indicate notational base).

And I hope that nobody comes to say that this is a trick !!!!
