For example 35=23+33. But 1,729 is the smallest number that has two different ways that it can be split into cube numbers. One way is to write it as 123+13 =1,728+1. But you can also express 1,729 as 103+93=1,000+729

Am I the only one who was really confused by this? There seems to be a character missing in there...

Yeah.

Code: [Select]

35 = 8 + 27
   = 2^3 + 3^3 (which I guess = 23 + 33)

But I'm guessing only computer people know that ^ means power of and superscript CSS would have been too difficult.

Or, it's under the women section and it just goes to show that women aren't very good with math.

Ahhh.. that makes a lot more sense, I was confused by that too.  So those equations should read 12^3+1^3=1728+1 and 10^3+9^3=1,000+729.

Yeah.

Code: [Select]

35 = 8 + 27
   = 2^3 + 3^3 (which I guess = 23 + 33)

But I'm guessing only computer people know that ^ means power of and superscript CSS would have been too difficult.

No it doesn't!  ^ is bitwise xor and anyone who says otherwise is a heathen!

I think the only real piece of handy maths is that 69 in fact equals 181
