635,318,657=a^4 + b^4 AND 635,315,657=c^4 + d^4. Find the four distinct integer values of a, b, c, d.
Thank you.
P. S. The number is the same number in both cases, namely: 635,318,657, despite the typo in the second one. Sorry about that.
WolramAlpha gives the following possible [paired] integer solutions :
±158, ±59
±134, ±133
You can mix and match them however you wish to get the pssible values for a, b, c and d
