Answer 2

HEYA!!

${a}^{6} + 27b^{3}$

$({a}^{2})^{3} + 27b^{3}$

using identity :

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

on substituting the values

we get,

$= ( {a}^{2} + 3b)( ({a}^{2})^{2} - {a}^{2} \times 3b + (3b)^{2} )$

$( {a}^{2} + 3b )( {a}^{4} - 3 {a}^{2}b + 9 {b}^{2} )$

hope it help!
