Salut!Nu mai scriu ex sa stii,e direct rezolvarea!!

$( \frac{26}{5 \sqrt{2} } + \frac{2}{ \sqrt{2} } ) - ( \frac{13}{ \sqrt{2} + } + \frac{3}{ \sqrt{2} } - \frac{5}{ \sqrt{2} }$

$\frac{36}{5 \sqrt{2} } - \frac{11}{ \sqrt{2} }$

$\frac{18 \sqrt{2} }{5} - \frac{11 \sqrt{2} }{2} </p><p>$

$- \frac{19 \sqrt{2} }{10} sau \: 2.68701$
