Am nevoie, va rog!!

Answer 1

Răspuns:

a) $\sqrt{\frac{1}{16} } : ( \sqrt{\frac{4}{9}} + \sqrt{\frac{49}{36}} - \sqrt{\frac{9}{144}} )$

$\frac{1}{4} : ( \frac{2}{3} + \frac{7}{6} - \frac{3}{12} ) \\\\\frac{1}{4} : ( \frac{8}{12} + \frac{14}{12} - \frac{3}{12} ) \\\\\frac{1}{4} : \frac{19}{12} \\\\\frac{1}{4} \cdot \frac{12}{19} = \frac{3}{19}$

b) $\sqrt{\frac{1}{64} } : ( \sqrt{\frac{100}{9} } - \sqrt{\frac{25}{16} } - \sqrt{\frac{9}{64} } )$

$\frac{1}{8} : ( \frac{10}{3} - \frac{5}{4} - \frac{3}{8} ) \\\\\frac{1}{8} : ( \frac{80}{24} - \frac{30}{24} - \frac{9}{24} ) \\\\\frac{1}{8} : \frac{41}{24} \\\\\frac{1}{8} \cdot \frac{24}{41} = \frac{3}{41}$

Sper ca te-am ajutat!
