niewiem czy o to chodzi…
|5-\sqrt{2}|=5-\sqrt{2} lub |5-\sqrt{2}|=-(5-\sqrt{2})=-5+\sqrt{2}=\sqrt{2}-5
|\sqrt{3}-3|=\sqrt{3}-3 lub |\sqrt{3}-3|=-(\sqrt{3}-3)=-\sqrt{3}+3=3-\sqrt{3}
|\sqrt{8}-\sqrt{10}|=\sqrt{8}-\sqrt{10} lub |\sqrt{8}-\sqrt{10}|=-(\sqrt{8}-\sqrt{10})=-\sqrt{8}+\sqrt{10}=\sqrt{10}-\sqrt{8}
