d
\(\sqrt{18}-\sqrt{6}\left(\sqrt{3}-\sqrt{24}\right)\\ =\sqrt{18}-\sqrt{6.3}+\sqrt{6.24}\\ =\sqrt{18}-\sqrt{18}+\sqrt{144}\\ =0+\sqrt{12^2}\\ =12\)
e
\(\sqrt{12}\left(\sqrt{5}-\sqrt{3}\right)-\sqrt{60}\\ =\sqrt{12.5}-\sqrt{12.3}-\sqrt{60}\\ =\sqrt{60}-\sqrt{60}-\sqrt{36}\\ =0-\sqrt{6^2}\\ =0-6\\ =-6\)
