Вычислить:
[tex]| \sqrt{5}-2.5 |+| \sqrt{5}-2 |[/tex]

Verified answer

$| \sqrt{5}-2.5 |+| \sqrt{5}-2 |=-( \sqrt{5})-2.5)+( \sqrt{5} -2)=$ $=- \sqrt{5} +2.5+ \sqrt{5} -2=0.5$

$| \sqrt{5}-2.5 |=-( \sqrt{5} -2.5)=- \sqrt{5} +2.5$ так как $\sqrt{5} \ \textless \ 2,5$
$| \sqrt{5}-2 |= \sqrt{5} -2$ так как $\sqrt{5} \ \textgreater \ 2$

$| \sqrt{5}-2.5|+| \sqrt{5} -2|=2.5- \sqrt{5}+ \sqrt{5}-2=2.5-2=0.5$
