Answer 1

Answer:

it is the smallest number that can be expressed as a sum of two cubes in two different ways: 1729 = 1728 + 1 = 123 + 13 1729 = 1000 + 729 = 103 + 93 1729 has since been known as the Hardy – Ramanujan Number, even though this feature of 1729 was known more than 300 years before Ramanujan.
