What is special about the number 1729?
It's the smallest number expressible as the sum of two cubes in two different ways." 1729 is the sum of the cubes of 10 and 9. Cube of 10 is 1000 and the cube of 9 is 729. Both the cubes, therefore, add up to 1729.Why 1729 number is very special?
Ramanujan said that it was not. 1729, the Hardy-Ramanujan Number, is the smallest number which can be expressed as the sum of two different cubes in two different ways. 1729 is the sum of the cubes of 10 and 9 - cube of 10 is 1000 and cube of 9 is 729; adding the two numbers results in 1729.Why 1728 is a special number?
In mathematics1728 is the cube of 12 and, as such, is important in the duodecimal number system, in which it is represented as "1000". It is the number of cubic inches in a cubic foot. 1728 occurs in the algebraic formula for the j-invariant of an elliptic curve.
What is the cube of 1729?
FAQs on Cube Root of 1729We can express 1729 as 7 × 13 × 19 i.e. ∛1729 = ∛(7 × 13 × 19) = 12.00231. Therefore, the value of the cube root of 1729 is 12.00231.
Why 1729 Is a Magic number example?
