Answer: x⁸ - 1/x⁸
Step by step explanation:
We'll use the identity: (a + b) (a - b) = a²- b².
Given: [x - 1/x] [x + 1/x] [x² + 1/x²] [x⁴ + 1/x⁴]
= [x² - 1/x²][x² + 1/x²][x⁴ + 1/x⁴]
= [(x²)² - (1/x²)²] [x⁴ + 1/x⁴]
= [x⁴- 1/x⁴] [x + 1/x⁴]
= (x⁴)² - (1/x⁴)²
= x⁸-1/x⁸
Thus, the answer is x⁸-1/x⁸.

Answer
We need to find the product
We know that :
(a + b)(a - b) = a² - b²
So,
⇛
We know that :
(a + b)(a - b) = a² - b²
⇛
We know that :
(a + b)(a - b) = a² - b²
⇛
i.e
