Question

FIND THE PRODUCT USING SUITABLE IDENTITY:-

☯️ DON'T SPAM! ​

Answer 1

Answer:

First we use the formula (a+b)(a-b)=a²-b²

Step-by-step explanation:

(x+1/x)(x-1x) = (x)²-(1/x)²

=( x² - 1/x² )

(x² - 1/x² ) (x² + 1/x²) = (x²)² - (1/x²)²

= x⁴ - 1/x⁴

(x⁴-1/x⁴) (x⁴ + 1/x⁴) = (x⁴)² -( 1/x⁴)²

= x⁸ - 1/x⁸

So the answer is x⁸ - 1/x⁸
