Answer
$g'(w)=25r^{4}+54r^{2}+2r+9$
Work Step by Step
$g(w)=(5r^{3}+3r+1)(r^{2}+3)$
$u=5r^{3}+3r+1$
$u'=5(3)r^{3-1}+3r^{1-1}+0$
$u'=15r^{2}+3r^0$
$u'=15r^{2}+3$
$v=r^{2}+3$
$v'=2r^{2-1}+0$
$v'=2r^{1}$
$v'=2r$
$g'(w)=u'v+uv'$
$g'(w)=(15r^{2}+3)(r^{2}+3)+(5r^{3}+3r+1)(2r)$
$g'(w)=15r^{4}+45r^{2}+3r^{2}+9+10r^{4}+6r^{2}+2r$
$g'(w)=25r^{4}+54r^{2}+2r+9$
