Sum and difference of two cubes is factored this way : a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2)
You get the sum of 11 two ways; 5,6 and 6,5.
23 = 8, 33 = 27. Sum 35, difference 19...
a3+ b3 = (a + b)(a2 - ab + b2)
According to Ramanujan, it's the lowest number that can be expressed in two different ways as the sum of two cubes (the cubes of 12 and 1; the cubes of 10 and 9). It 's the answer.
