Answer:

<b><fontface=Copperblacksize=4colour=purple>

< b > < marquee direction = "up" > < h3 ><b><marqueedirection="up"><h3> Given⁴ - y⁴

= ( x² )² - ( y² )²

{ Using identity

a² - b² = ( a + b ) ( a - b ) }

= ( x² + y² ) ( x² - y² )

Again using the identity

= ( x² + y² ) [ ( x )² - ( y )² ]

= ( x² + y² ) ( x + y ) ( x - y )
