[tex]2 \times \frac{3}{9} \times \sqrt{ \frac{1}{9} } + \sqrt{ \frac{324}{25} } \div \sqrt{ \frac{81}{225} } - \sqrt{1024} \div \sqrt{64} = [/tex]
[tex]2 \times \frac{1}{3} \times \frac{1}{3} + \frac{ \sqrt{324} }{5} \times \frac{ \sqrt{225} }{9} - 32 \div 8[/tex]
[tex] \frac{2}{9} + \frac{18}{5} \times \frac{15}{9} - 4 = [/tex]
(simplificam 18 cu 9 și 15 cu 5)》
[tex] \frac{2}{9} + \frac{2}{1} \times \frac{3}{1} - 4 = [/tex]
[tex] \frac{2}{9} + 6 - 4 = [/tex]
[tex] \frac{2}{9} + 2[/tex]
[tex] \frac{2}{9} + \frac{2}{1} [/tex]
amplificam cu 9 pe
[tex] \frac{2}{1} [/tex]
[tex] \frac{2 + 18}{9} = \frac{20}{9} [/tex]
