Find the smallest number that can be expressed as the sum of two (nonzero) perfect squares in two different ways.
_____________

And what if the two perfect squares must be nonzero, positive, and different?

Penny,
In my books, sharing some related information does not make the post wrong.

According to your theory, those who presented more than one answer would also be wrong, because the question requires the SMALLEST number. We read those posts with interest because the additional infformation is related.

In closing, I must say I enjoy all your posts, and I congratulate you for suggesting the fourth way to solving a problem, which I believe is the most illuminating way!

Best regards.
