answer with explanation plz​

Answer 1

Answer:

Answer:

-a⁸ + b⁸ = (b⁴ + a⁴)(b² + a²)(b + a)(b - a)

Step-by-step explanation:

Factorise :- a 8 + b 8

-a⁸ + b⁸

= b⁸ - a⁸

= (b⁴)² - (a⁴)²

Using x² - y² = ( x+ y)(x -y)

here x = b⁴ & y = a⁴

= (b⁴ + a⁴)(b⁴ - a⁴)

= (b⁴ + a⁴)( (b²)² - (a²)²)

= (b⁴ + a⁴)(b² + a²)(b² - a²)

= (b⁴ + a⁴)(b² + a²)(b + a)(b - a)

-a⁸ + b⁸ =
