Question

use identity and solve X ^ 8 - Y ^ 8​

Answer 1

Answer:

x^8y^8 is your answer

Step-by-step explanation:

first we multiply

x^8*y^8

it is unlike variable so

x^8y^8

Answer 2

Answer:

(x⁴ + y⁴) (x² + y²) (x + y) (x - y)

Step-by-step explanation:

x⁸ - y⁸

⇒ (x⁴)² - (y⁴)² {• (a⁴)² = x⁸ }

⇒ (x⁴ + y⁴) (x⁴ - y⁴)

⇒ (x⁴ + y⁴) [ (x²)² - (y²)² ] {• (a²)² = a⁴ }

⇒ (x⁴ + y⁴) (x² + y²) (x² - y²) {• a²-b² = (a+b) (a-b) }

⇒ (x⁴ + y⁴) (x² + y²) (x + y) (x - y)
