Salutare!
[tex] \frac{ \sqrt{3} }{2.(3)} + \frac{3}{1.25} - \frac{ \sqrt{3} }{1.1(6)} [/tex]
[tex]2.(3) = \frac{23 - 2}{9} = \frac{21}{9} [/tex]
[tex]1.1(6) = \frac{116 - 11}{90} = \frac{105}{90} = \frac{7}{6} [/tex]
[tex]1.2 5= \frac{5}{4} [/tex]
[tex] \frac{ \frac{ \sqrt{3} }{21} }{9} + \frac{ \frac{ \sqrt{3} }{5} }{4} - \frac{ \frac{ \sqrt{3} }{7} }{6} = \frac{ \sqrt{3} }{189} + \frac{4 \sqrt{3} }{5} - \frac{ \sqrt{3} }{42} = amplificare \: cu \: 10 = \frac{10 \sqrt{3} }{1890} + \frac{1512 \sqrt{3} }{1890} - \frac{45 \sqrt{3} }{1890} = \frac{1477 \sqrt{3} }{1890} = simplificare \: cu \: 7 \: = \frac{211 \sqrt{3} }{270} [/tex]
