Question

simplify: (a2+5) (b3+3) +5​

Answer 1

$({a}^{2} + 5)( {b}^{3} + 3) + 5 \\ \\ = > {a}^{2} {b}^{3} + 3{a}^{2} + 5{b}^{3} + 15 + 5 \\ \\ = > {a}^{2} {b}^{3} + 3{a}^{2} + 5{b}^{3} + 20$

Answer 2

$( {a}^{2} + 5)( {b}^{3} + 3) + 5$

$= {a}^{2} ( {b}^{3} + 3) + 5( {b}^{3} + 3) + 5$

$= {a}^{2} {b}^{3} + 3 {a}^{2} + 5 {b}^{3} + 15 + 5$

$= {a}^{2} {b}^{3} + 3 {a}^{2} + 5 {b}^{3} + 20$
