Question

(a)^4 - (b)^4 evaluate​

Answer 1

Answer:

a^4-b^4.

you can also write it as (a^2)^2-(b^2)^2.

now, by identity a^2-b^2= (a+b)(a-b) we will solve it further.

so, (a^2-b^2)(a^2+b^2).

or, further, (a-b)(a+b)(a^2+b^2).

Answer 2

Step-by-step explanation:

    (a)⁴ - (b)⁴

⇒ a⁴-b⁴

= (a²)² - (b²)²

= (a²+b²) ( a²-b²)

= (a²+b²) (a+b) (a-b)
