Answer: The required factored form of the given expression is
(2x^8-3y^2)(4x^(16)+6x^8y^2+9y^4).

Step-by-step explanation: We are given to find the factored form of the following expression :


E=8x^(24)-27y^6.

We will be using the following factorization formula :


a^3-b^3=(a-b)(a^2+ab+b^2).

So, the factorization of the given expression is as follows :


E\\\\=8x^(24)-27y^6\\\\=(2x^8)^3-(3y^2)^3\\\\=(2x^8-3y^2)((2x^8)^2+2x^8*3y^2+(3y^2)^2)\\\\=(2x^8-3y^2)(4x^(16)+6x^8y^2+9y^4).

Thus, the required factored form of the given expression is
(2x^8-3y^2)(4x^(16)+6x^8y^2+9y^4).
