Answer 2

Given:

${a}^{3} + 512$

To find:

the solution

STEP BY STEP EXPLANATION:

${a}^{3} + 512$

write the number in the exponential form with an exponent of 3

${a}^{3} + {8}^{3}$

using ${a}^{3} + {b}^{3} = (a + b)( {a}^{2} - ab + {b}^{2} )$ factor the expression

$(a + 8) \times ( {a}^{2} - a \times 8 + {8}^{2} )$

use the commutative property to recorder the terms

$(a + 8) \times ( {a}^{2} - 8a + {8}^{2} )$
