**NCERT Solutions Chapter 7 ****Cubes and Cube Roots**

This is a story about one of India’s great mathematical geniuses, S. Ramanujan. Once

another famous mathematician Prof.G.H. Hardy came to visit him in a taxi whose number was 1729. While talking to Ramanujan, Hardy described this number “a dull number”. Ramanujan quickly pointed out that 1729 was indeed interesting. He said 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.
