Answer 2

Answer:

$we \: should \: use \: the \: identity \: ( {a - b})^{3}$

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

$= ( {5a}^{3} - {3}^{3} - 3( {5a}^{2} \times 3) + 3(5a \times {3}^{2})$

$= 125 {a}^{3} - 27 - 225 {a}^{2} + 135a$

$therefore$

$( {5a - 3}^{3} ) \: is \: the \: answer$
