- 2025 = 3⁴5² This makes 2025 a year whose factorization into primes contains the four consecutive digits 2, 3, 4 and 5, with each appearing exactly once. The last time this happened was 2000 = 2⁴5³. I believe the next time will be 3888 = 2⁴3⁵. Extra credit for the non-solution, 4³2⁵ = 2¹¹ = 2048.
- actually a fact that doesn't rely on digits notation right? that makes it better :)Dec 19, 2024 16:47
