Answer 1

Answer:

$\huge\color{blue}\boxed{\colorbox{yellow}{b) (x⁴-y⁴)}}$

Explanation:

$( \sqrt{ {x} } + \sqrt{y}) ( \sqrt{x} - \sqrt{y})(x + y)( {x}^{2} + {y}^{2} )$

By using Identity (a+b)(a-b) = a²-b²

$( \sqrt{ {x}^{2} } - \sqrt{ {y}^{2} })(x + y)( {x}^{2} + {y}^{2} )$

cancel root (√) by square (²)

$(x - y)(x + y)( {x}^{2} + {y}^{2} )$

Again by using identity (a+b)(a-b) = a²-b²

$({x}^{2} - {y}^{2})( {x}^{2} + {y}^{2} )$

One more time put identity (a+b)(a-b) = a²-b²

$( { {x}^{2} })^{2} - ( { {y}^{2} })^{2}$

$={x}^{4} - {y}^{4}$

Answer is:

$\large\mathcal\fcolorbox{pink}{pink}{(x⁴-y⁴)}$
