Answer 1

Explicație pas cu pas:

a)

$\frac{2}{ \sqrt{10} } + \frac{5 \sqrt{2} }{2 \sqrt{5} } - ( \frac{2 \sqrt{5} }{ \sqrt{8} } + \frac{5 \sqrt{2} }{125} )$

$\frac{ \sqrt{10} }{5} + \frac{ \sqrt{10} }{2} - ( \frac{2 \sqrt{5} }{2 \sqrt{2} } + \frac{ \sqrt{2} }{25}$

$\frac{ \sqrt{10} }{5} + \frac{ \sqrt{10} }{2} - ( \frac{ \sqrt{5} }{ \sqrt{2} } + \frac{ \sqrt{2} }{25} )$

$\frac{ \sqrt{10} }{5} + \frac{ \sqrt{10} }{2} - ( \frac{ \sqrt{10} }{2} + \frac{ \sqrt{2} }{25} )$

$\frac{ \sqrt{10} }{5} - \frac{ \sqrt{2} }{25}$

b)

$\frac{2 \sqrt{2} }{3 \sqrt{3} } + \frac{5 \sqrt{2} }{2 \sqrt{3} } - ( \frac{7 \sqrt{2} }{6 \sqrt{3} } + \frac{4 \sqrt{2} }{ \sqrt{3} } )$

$\frac{2 \sqrt{6} }{9} + \frac{5 \sqrt{6} }{6} - \frac{31 \sqrt{2} }{6 \sqrt{3} }$

$\frac{2 \sqrt{6} }{9} + \frac{5 \sqrt{6} }{6} - \frac{31 \sqrt{6} }{18}$

$- \frac{2 \sqrt{6} }{3}$
