Salutare!

$\bf 30^ {n+3} :10^{n+3} -3^{n}\cdot 3^{3}=$

$\bf 3^{n+3}\cdot 10^{n+3} :10^{n+3} -3^{n}\cdot 3^{3}=$

$\bf 3^{n+3}\cdot 10^{n+3-(n+3)} -3^{n+3}=$

$\bf 3^{n+3}\cdot 10^{n+3-n-3} -3^{n+3}=$

$\bf 3^{n+3}\cdot 10^{0} -3^{n+3}=$

$\bf 3^{n+3}\cdot 1 -3^{n+3}=$

$\bf 3^{n+3} -3^{n+3}= \boxed{\bf 0}$
