Question

iska answer hai
$a {8 - 16}^{?}$
​

Answer 1

Answer:

a⁸ - 16

Step-by-step explanation:

$(a^2+2)(a^2-2)(a^4 + 4)\\\\\\= (a^4 - 4)(a^4 + 4)\\\\\\= (a^8) - 4^2\\\\\\= a^8 - 16$

$\text{Identities used:}\\\\(a+b)(a-b) = a^2 - b^2$

Answer 2

Answer:

a^8-16

Step by Step explanation :

(a²+2)(a²-2)(a⁴+4)

We know the identity (a+b)(a-b)=a²-b²

Using this identity :

(a⁴-4)(a⁴+4)

Again this expression is of the form (a+b)(a-b). So, by again using the same identity we get :-

(a⁴)²-4² = a^8-16
