a3+ b3 = (a + b)(a2 - ab + b2)
1729 is the smallest number that can be expressed in two ways as the sum of two cubes.[12cube+9cube] * * * * * ... two positive cubes. 12 cube + 1 cube and 10 cube + 9 cube.
a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2
(a3 + b3) = (a + b)(a2 - ab + b2)
The expression a^3 + b^3 can be factored using the sum of cubes formula, which states that a^3 + b^3 = (a + b)(a^2 - ab + b^2). Therefore, a^3 + b^3 can be factored as (a + b)(a^2 - ab + b^2). This formula helps us break down the sum of two cubes into a product of binomials, simplifying the expression.
(xy + 7)(x^2y^2 - 7xy + 49)
The sum of two cubes can be factored as below.a3 + b3 = (a + b)(a2 - ab + b2)
That means that you calculate the cubes of two numbers, and then either add or subtract them.

The sum of their squares is 10.
Sum and difference of two cubes is factored this way : a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2)

The sum or difference of two cubes refers to the algebraic expressions (a^3 + b^3) and (a^3 - b^3). The sum of cubes can be factored as ((a + b)(a^2 - ab + b^2)), while the difference of cubes can be factored as ((a - b)(a^2 + ab + b^2)). These factorizations are useful in simplifying polynomial expressions and solving equations involving cubic terms.
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.
