HI !
I think the question is wrong, It should be x⁸ - y⁸
x⁸ - y⁸
This can be written in the form of identity (a-b)(a+b) =a² - b²
= (x⁴)² - (y⁴)²
= (x⁴ + y⁴) (x⁴ - y⁴)
(x⁴ - y⁴) can be written in the form of identity (a-b)(a+b) =a² - b²
= (x⁴ + y⁴) ({x²}² - {y²}²)
= (x⁴ + y⁴) {x² + y²} {x² - y²}
{x² - y²} can be written as (x+y) (x -y) { identity}
= (x⁴ + y⁴) {x² + y²} {x+y} { x- y}
Hope this helps you !
