Найдите модуль числа: а)  |1-[latex] \sqrt{2} [/latex];    в) |2,2 - [latex] \sqrt{5} [/latex]|; б)|[latex] \sqrt{3} [/latex]-[latex] \sqrt{2} [/latex]|;    г) |[latex] \sqrt{6} [/latex] — 2,5|.

[latex]|1-\sqrt{2}|=|\sqrt{1}-\sqrt{2}|=\sqrt{2}-\sqrt{1}=\sqrt{2}-1[/latex] [latex]|2.2-\sqrt{5}|=|\sqrt{4.84}-\sqrt{5}|=\sqrt{5}-2.2[/latex] [latex]|\sqrt{3}-\sqrt{2}|=\sqrt{3}-\sqrt{2}[/latex] [latex]|\sqrt{6}-2.5|=\sqrt{6}-\sqrt{6.25}|=2.5-\sqrt{6}[/latex]
