$$=\frac{{sqrt}\left(\mathrm{1}+\mathrm{7}\right)−{sqrt}\left(\mathrm{3}+\mathrm{5}\right)}{{sqrt}\left(\mathrm{3}+\mathrm{1}\right)−{sqrt}\left(\mathrm{5}+\mathrm{3}\right)} \\ $$$$=\frac{{sqrt}\left(\mathrm{8}\right)−{sqrt}\left(\mathrm{8}\right)}{{sqrt}\left(\mathrm{4}\right)−{sqrt}\left(\mathrm{8}\right)} \\ $$$$=\frac{\mathrm{0}}{{sqrt}\left(\mathrm{4}\right)−{sqrt}\left(\mathrm{8}\right)} \\ $$$$=\mathrm{0} \\ $$
