Answer:
(3) 88
Step-by-step explanation:
44² = 1936 < 2007 < 2025 = 45²
Since y is a natural number, it must be one of
1, 2, 3, 4, ..., 44.
For each y, there are then two possibilities for the real number x:
x = √(2007 - y²) and x = -√(2007 - y²).
Notice that these are different numbers since it's never 0 because 2007 is not a perfect square.
So 44 choices for y and, for each of those, 2 choices for x, give
44 × 2 = 88 solutions in total.
