$$\left(\mathrm{2}{x}\right)^{\mathrm{4}} +\mathrm{324}=\left(\mathrm{4}{x}^{\mathrm{2}} −\mathrm{12}{x}+\mathrm{18}\right)\left(\mathrm{4}{x}^{\mathrm{2}} +\mathrm{12}{x}+\mathrm{18}\right) \\ $$$${f}\left({x}\right)=\mathrm{4}{x}^{\mathrm{2}} −\mathrm{12}{x}+\mathrm{18}\Rightarrow{f}\left({x}+\mathrm{3}\right)=\mathrm{4}{x}^{\mathrm{2}} +\mathrm{12}{x}+\mathrm{18} \\ $$$$\left(\mathrm{2}{x}\right)^{\mathrm{4}} +\mathrm{324}={f}\left({x}\right)\centerdot{f}\left({x}+\mathrm{3}\right) \\ $$$$\frac{{f}\left(\mathrm{5}\right){f}\left(\mathrm{8}\right){f}\left(\mathrm{11}\right){f}\left(\mathrm{14}\right){f}\left(\mathrm{17}\right){f}\left(\mathrm{20}\right){f}\left(\mathrm{23}\right){f}\left(\mathrm{26}\right){f}\left(\mathrm{29}\right){f}\left(\mathrm{32}\right)}{{f}\left(\mathrm{2}\right){f}\left(\mathrm{5}\right){f}\left(\mathrm{8}\right){f}\left(\mathrm{11}\right){f}\left(\mathrm{14}\right){f}\left(\mathrm{17}\right){f}\left(\mathrm{20}\right){f}\left(\mathrm{23}\right){f}\left(\mathrm{26}\right){f}\left(\mathrm{29}\right)}=\frac{{f}\left(\mathrm{32}\right)}{{f}\left(\mathrm{2}\right)}=\mathrm{373} \\ $$$$ \\ $$$$ \\ $$
