1.

(x²+1/x²)(x²-1/x²) ,Use suitable identities to find the given product.

Answer» SOLUTION :

*****************************************
We KNOW the ALGEBRAIC IDENTITY :

( a + B )( a - b ) = a² - b²

*****************************************

Now ,

( x² + 1/x² )( x² - 1/x² )

= ( x² )² - ( 1/x² )²

= x⁴ - 1/x⁴
