 Cubic AND Quartic Challenge (Posted on 2004-02-06)
What is the smallest positive integer that is the sum of two different pairs of (non-zero, positive) cubes?
_____________________________

What is the smallest positive integer that is the sum of two different pairs of integers raised to the 4th power? and how did you find it?

In other words what is the smallest x such that:
x = a^4 + b^4 = c^4 + d^4
(where x, a, b, c, and d are all different, non-zero, positive integers)?
_____________________________

Are you able to determine the answer without looking it up on the internet?

hehe, okay, so I missed the "root". But, your original message seemed to pooh pooh Gamer's reply, and you even commented that you couldn't tell what he meant because of the errors! So, do you get it or not?
