📰 Thus, the value is $ oxed{133} $.Question: How many lattice points lie on the hyperbola $ x^2 - y^2 = 2025 $? 📰 Solution: The equation $ x^2 - y^2 = 2025 $ factors as $ (x - y)(x + y) = 2025 $. Since $ x $ and $ y $ are integers, both $ x - y $ and $ x + y $ must be integers. Let $ a = x - y $ and $ b = x + y $, so $ ab = 2025 $. Then $ x = rac{a + b}{2} $ and $ y = rac{b - a}{2} $. For $ x $ and $ y $ to be integers, $ a + b $ and $ b - a $ must both be even, meaning $ a $ and $ b $ must have the same parity. Since $ 2025 = 3^4 \cdot 5^2 $, it has $ (4+1)(2+1) = 15 $ positive divisors. Each pair $ (a, b) $ such that $ ab = 2025 $ gives a solution, but only those with $ a $ and $ b $ of the same parity are valid. Since 2025 is odd, all its divisors are odd, so $ a $ and $ b $ are both odd, ensuring $ x $ and $ y $ are integers. Each positive divisor pair $ (a, b) $ with $ a \leq b $ gives a unique solution, and since 2025 is a perfect square, there is one square root pair. There are 15 positive divisors, so 15 such factorizations, but only those with $ a \leq b $ are distinct under sign and order. Considering both positive and negative factor pairs, each valid $ (a,b) $ with $ a 📰 e b $ contributes 4 lattice points (due to sign combinations), and symmetric pairs contribute similarly. But since $ a $ and $ b $ must both be odd (always true), and $ ab = 2025 $, we count all ordered pairs $ (a,b) $ with $ ab = 2025 $. There are 15 positive divisors, so 15 positive factor pairs $ (a,b) $, and 15 negative ones $ (-a,-b) $. Each gives integer $ x, y $. So total 30 pairs. Each pair yields a unique lattice point. Thus, there are $ oxed{30} $ lattice points on the hyperbola. 📰 How Many Powerball Numbers 8008663 📰 Jean Jacket Sherpa Womens 8339603 📰 Top 10 Nc 17 Movies You Need To Watch Before They Disappear Forever Controversial Compulsive 9687144 📰 Solve For R 1914731 📰 Where To Watch Carolina Panthers Vs Arizona Cardinals 3233483 📰 Nutritional Content Of Collard Greens 1456267 📰 Link And Toon Link 6035846 📰 Youll Be Astonished By These Secret Kokeshi Dolls Hidden In Japanese Folk Art 9481908 📰 Pinky Tuscadero 297996 📰 Dealey Plaza Assassin Positions 7484764 📰 Youre Suffering Sound Quality Heres The Ultimate Mic Troubleshooting Guide 3478613 📰 No Actual False Claimsjust Optimized Engaging Phrasing For Clicks 5098724 📰 Heaven Studio 6603529 📰 Email Wells Fargo Customer Service 585126 📰 The Truth About Tinas Movie No One Expected It Ruined Careers And Sparked Chaos 4667978
