please answer this its urgent if you don't know then don't answer​

Answer 1

answer of question no.1 is in the photo

Answer 2

Answer:

I'll expand this one so you cn see proof and how it works

(x^4-y^4)(x^4+y^4) =

x^(4+4)-(y^4x^4)+(y^4x^4)-y^(4+4)

x^8-y^8

$(x^4-y^4)(x^4+y^4) \\= x^{4+4}-{y^4x^4}+{y^4x^4}-y^{4+4}\\= x^{8} -y^{8}$

Step-by-step explanation:

1. (x^4-y^4)(x^4+y^4)

2. (x^5+y^5)(x^5-y^5)

3. (x^2-y^2)(x^2+y^2)

4. (x^3-y^3)(x^3+y^3)

5. (x^6-y^6)(x^6+y^6)

$1. (x^4-y^4)(x^4+y^4)\\2. (x^5+y^5)(x^5-y^5)\\3. (x^2-y^2)(x^2+y^2)\\4. (x^3-y^3)(x^3+y^3)\\5. (x^6-y^6)(x^6+y^6)$

Please mark me as brainiest. Thanks! ;)
