(a+1/a)(a-1/a)(a²+1/a²)(a⁴+1/a⁴)

=[(a+1/a)(a-1/a)](a²+1/a²)(a⁴+1/a⁴)

=[a²-(1/a)²](a²+1/a²)(a⁴+1/a⁴)

=[(a²-1/a²)(a²+1/a²)](a⁴+1/a⁴)

= [(a²)²-(1/a²)²](a⁴+1/a⁴)

= (a⁴-1/a⁴)(a⁴+1/a⁴)

= (a⁴)²-(1/a⁴)²

Therefore,

(a+1/a)(a-1/a)(a²+1/a²)(a⁴+1/a⁴) =

Answer:

a^8 - \frac{1}{a^8}

Step-by-step explanation:

(a - \frac{1}{a} ) ( a + \frac{1}{a} ) (a^2 + \frac{1}{a^2}) (a^4 + \frac{1}{a^4} )

(a^2 - \frac{1}{a^2}  ) (a^2 + \frac{1}{a^2}  ) (a^4 + \frac{1}{a^4} )      [ (a+b) (a-b) = a^2 - b^2]

(a^4 - \frac{1}{a^4}) (a^4 + \frac{1}{a^4} )

a^8 - \frac{1}{a^8}
