$(3)$ Put each statement in order of complexity in each Big$-$Oh equation.

$(3.$Ex$)O(n)=5800+5n^4+17n$

$5n^4+17n+5800,$ Polynomial complexity $O(n^2)$ is highest order

$(3\mathrm{.}1)O(n)=3n+2n!+{2000}^n$

$(3\mathrm{.}2)O(n)=25n+7n+14n$

$(3\mathrm{.}3)O(n)=(2n{)}^2+3log(n)+27n$

$(3\mathrm{.}4)O(n)=2nlog(n)+54n+320$

$(3\mathrm{.}5)O(n)=5^n+n^{780}+42$

$(3\mathrm{.}6)$ Put the results of $(3\mathrm{.}1),(3\mathrm{.}2),(3\mathrm{.}3),(3\mathrm{.}4),$ and $(3\mathrm{.}5)$ in order from Least Complex to Most
