Answer 1

b ) (a^8 - b^8) by (a^2 + b^2)

ans. (a^8 - b^8) = (a^4)^2 - (b^4)^2

= (a^4 + b^4)(a^4 - b^4) =  (a^4 + b^4)[(a^2)^2 - (b^2)^2]

= (a^4 + b^4)(a^2 - b^2)(a^2 + b^2)

divide this eq. by  (a^2 + b^2) we get ,

(a^4 + b^4)(a^2 - b^2) = (a^4 + b^4)(a - b)(a + b)

Answer 2

Answer:

hi dear .

Step-by-step explanation:

a⁸-b⁸=(a⁴+b⁴) (a⁴)²- (b⁴)

a⁸-8⁸= (a⁴-b⁴) (a⁴-b⁴ )

= a⁴+b⁴ { a²)²-(b²)²}

= (a⁴+b⁴ ) (a²+b²) (a²-b² )

= ( a⁸- b⁸) / (a²+b²)

= ( a⁴+b⁴) ( a²+b²) ( a²-b²)

= a⁴+b⁴) (a² -b²)

hope u understand
