Question

simplify (a^2+5)(b^2+3)+5​

Answer 1

Answer:

a² (b³ + 3) + 5 ( b³ + 3 ) + 5

Step-by-step explanation:

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

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

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

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