The answer will depend on what you mean by "do the sum". Why not simply add them together?

For example 93 = 729 and 103 = 1000 so 93 + 103 = 729 + 1000 = 1729.

NB: Totally irrelevant to the question, but the above example is the smallest integer that can be expressed as a sum of two positive cubes in two different ways - as Ramanujan was to inform the Cambridge (UK) mathematician Hardy.

What does sum of cubes mean?

X3 + a3 = (X + a)(X2- aX + a2)Just a formula so that when you see an expression of any value that is additive cubes ( on the left ) then you can factor it. Works in any direction and some expressions can be manipulated into this form for factoring.
