[tex](( \frac{ \sqrt{2} }{5} \times ( \frac{1}{ \sqrt{2} } + \frac{2}{3 \sqrt{2} } )) + (( \frac{1}{ \sqrt{2} } - 3/3 radical din 2) \div \frac{1}{5 \sqrt{2} } )) \div 2 \\ = (( \frac{ \sqrt{2} }{5} \times \frac{5}{3 \sqrt{2} } ) + ( \frac{1}{3 \sqrt{2} } \times 5 \sqrt{2} )) \div 2 \\ = ( \frac{1}{3} + ( \frac{1}{3} \times 5)) \div 2 \\ = ( \frac{1}{3} + \frac{5}{3} ) \div 2 \\ = \frac{6}{3} \div 2 \\ = 2 \div 2 \\ = 1[/tex]
