a: \(3+\sqrt{3}=\sqrt{3}\left(\sqrt{3}+1\right)\)
b: \(10+2\sqrt{10}=\sqrt{20}\left(\sqrt{5}+\sqrt{2}\right)\)
c: \(\sqrt{14}-\sqrt{7}=\sqrt{7}\left(\sqrt{2}-1\right)\)
d: \(\sqrt{15}-\sqrt{6}=\sqrt{3}\left(\sqrt{5}-\sqrt{2}\right)\)
e: \(5\sqrt{3}-3\sqrt{5}=\sqrt{15}\left(\sqrt{5}-\sqrt{3}\right)\)
