If positive integers x and y satisfy the equation √ x + √ y = √ 2007, try to find the value of X + y


Because 2007 = 3 * 3 * 223, so √ 2007 = 3 √ 223, because √ x + √ y = √ 2007, √ x + √ y = 3 √ 223, and only the same kind of quadratic radical can be merged, so let √ x = m √ 223, √ y = n √ 223, so m √ 223 + n √ 223 = 3 √ 223, so m + n = 3, because m, n are positive integers, so m = 1, n = 2 or M = 2, n =
