Question

factorize x4y4 - 256z4 please answer

Answer 1

x4y4 - 256z4
(xy)4 - (4z)4
${( {xy}^{2} })^{2} - { ({4z}^{2} })^{2}$
using identity
${a}^{2} - {b}^{2} = (a + b)(a - b)$

$( {xy}^{2} + {4z}^{2} )( {xy}^{2} - {4z}^{2} )$
$( {xy}^{2} + {4z}^{2} )(xy + 4z)(xy - 4z) \: is \: the \: answer \: of \: ths \: question$
it is the answer of this question
please mark as brainliest answer plzzzzz
