------>>>>Here is your answer<<<<--------

$➪ {(8x)}^{3} + {(729y)}^{3} = {(2x)}^{3} + {(9y)}^{2}$

$➪ {(2x)}^{3} + {(9y)}^{3}$

we use this formula to solve:-

$➪ {a}^{3} + {b}^{3} = (a + b)( {a}^{2} - ab + {b}^{2} )$

$➪ {(2x)}^{3} + {(9y)}^{3} = (2x + 9y)( {(2x)}^{2} + {(9y)}^{2} -( 2x)(9y))$

HOPE IT HELPS YOU..
