The sum of cubes formula:

[tex](a+b)(a^2+2ab+b^2)[/tex]

[tex](5x^3+4y^4)(25x^6+40x^3y^4+16y^8)[/tex]

The cube form is (5x³)³ + (4y^4)³.

What is Factorization?

Given:

125[tex]x^{9}[/tex] + 64 [tex]y^{12}[/tex]

Now, we can write it as

(5x³)³ + (4y^4)³

Hence, the cube form is (5x³)³ + (4y^4)³.
