Answer 2

Step-by-step explanation:

As we know that, any number x qualifies as a Hardy Ramanujan number, if

x=a³+b³=c³+d³

Where a, b , c and d are 4 different positive numbers. This combination is very rare.

If we try one by one option given, then for 13832, we can find two such pairs of numbers.

First pair is 2 and 24, because

13832=2³+4³

13832=8+13824

⇒13832=13832

hen second pair is 18 and 20, because

13832=18³+20³.

⇒13832=5832+8000

⇒13832=13832

It is clear that 13832 is the given Hardy Ramanujan number.
