First of all I apologise if this is not the correct site of my question.
I work on a mathematical issue and I am curious if is valid the following:
a^2+b^2 != c^2+d^2
(where a,b,c,d integers and != is the sumbol of inequality).
Thank you all for your time and your response
Hi, thank you for your time
'Are you claiming that the sum of two squares cannot be the sum of two other squares?'
Indeeed that exactly i am claiming. However as i more carefully noticed, this is not valid. Besides your counter example is definite.
Thank you again
