a, b, and x are positive integers such that
sqrt(a) + sqrt(b) = sqrt(x)
How many possible values of x less than or equal to 1000 are there?
Making a computer program that evaluates for a from 1 to 999, and b from 1 to (sqrt(1000)-sqrt(a))^2, and eliminating multiple solutions of x, I got
211 solutions.
