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.
There is a formula for the sum of cubes. In this case, it's (b + 1)(b^2 - b + 1)
(2x - 5y)(4x^2 + 10xy + 25y^2)
a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2)
factor out the common monomial, 5. 5(r^3-1) Factor as a difference of cubes. 5(r-1)(r^2+r+1)
The difference of cubes has a formula. (4x - y)(16x2 + 4xy + y2)
Do in this order. 1. All, find the gfc 2. Binomial, factor as difference of squares, sum of cubes, difference of cubes. 3. Trinomial, factor as a quadratic. 4. 4 or more terms, factor by grouping.
First, you can take out the common factor "x".For what remains (the factor other than "x"), you can use the formula for the difference of two cubes.
A sum that is a factor of 6 has a greater probability.to my dick
Sum and difference of two cubes is factored this way : a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2)
all perfect cubes (any number powered by 3) by adding or subtracting 1 become factor of 7 except base number as 7 and its factors.
There's a formula for the sum of cubes. (3x + 4)(9x^2 - 12x + 16)
(xy + 7)(x^2y^2 - 7xy + 49)
factoring whole numbers,factoring out the greatest common factor,factoring trinomials,factoring the difference of two squares,factoring the sum or difference of two cubes,factoring by grouping.
There is a formula for the sum of cubes. In this case, it's (b + 1)(b^2 - b + 1)
1, 8, 27, 64, 125 are the only cubes under 180. 1 is the only factor.
(2x - 5y)(4x^2 + 10xy + 25y^2)
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.
