Question

x^4-y^4








if you give correct answer I will press as a brilliant answer ​

Answer 1

Answer:

(x²)² -(y²) ²

= (x²+y²) (x²-y²)

Answer 2

Answer:

${x}^{4} - {y}^{4} \\ =(( x) {}^{2} ) {}^{2} - ((y) {}^{2} ) {}^{2} \\ = ( {x}^{2} + {y}^{2})( {x}^{2} - {y}^{2} ) \\ = ( {x}^{2} + {y}^{2} )((x) {}^{2} - (y) {}^{2} ) \\ = ( {x}^{2} + {y}^{2} )(x + y)(x - y) \\ \\ formula \\ {a}^{2} - {b}^{2} = (a + b)(a - b)$
