Answer 1

Răspuns:

Deci....

$\frac{8}{ \sqrt{200} } + \frac{10}{ \sqrt{450} } - \frac{2}{ \sqrt{18} } - \frac{2}{ \sqrt{50} } =$

$\frac{8}{10 \sqrt{2} } + \frac{10}{15 \sqrt{2} } - \frac{2}{3 \sqrt{2} } - \frac{2}{5 \sqrt{2} } =$

$\frac{4}{5 \sqrt{2} } + \frac{2}{3 \sqrt{2} } - \frac{2}{3 \sqrt{2} } - \frac{ \sqrt{2} }{5} =$

$\frac{2 \sqrt{2} }{5} - \frac{ \sqrt{2} }{5} =$

$\frac{ \sqrt{2} }{5}$

Succes....
