If \(\sqrt{x}\) and \(\sqrt{y}\) are nonzero integers, what is the remainder when x is divided by y?
(1) \(\sqrt{x} - \sqrt{y}= 1\)
(2) x–y is a positive integer.
(1) \(\sqrt{x} - \sqrt{y}= 1\)
(2) x–y is a positive integer.

If \(\sqrt{x}\) and \(\sqrt{y}\) are nonzero integers, what is the remainder when x is divided by y?
This tells us that x and y are perfect squares, so
a) If y>x, then the remainder is x.
b) If x>y, then we require both values.
(1) \(\sqrt{x} - \sqrt{y}= 1\)
This tells us that \(\sqrt{x}\) and \(\sqrt{y}\) are consecutive integers.
If they are 2 and 1, then the answer is 4 divided by 1 gives a remainder 0.
If they are 3 and 2, then the answer is 9 divided by 4 gives a remainder 1.
(2) x–y is a positive integer.
Nothing new. x>y
Combined
Nothing new.
the cases in statement I still stand.
