Question

1Se consideră numărul rațional pozitiv x = 10 -12-09] 3 5 2​

Answer 1

Explicație pas cu pas:

$x = \frac{11}{10} - \Big[2 \frac{1}{3} - {\Big( \frac{1}{2} \Big)}^{2} \Big] : \frac{5}{2} = \frac{11}{10} - \Big(\frac{^{4)} 7}{3} - \frac{^{3)}1}{4}\Big) \cdot \frac{2}{5} = \frac{11}{10} - \frac{28 - 3}{12} \cdot \frac{2}{5} = \frac{11}{10} - \frac{\not25^{5}}{\not12_{6}} \cdot \frac{ \not2}{\not5} = \frac{^{3)}11}{10} - \frac{^{5)}5}{6} = \frac{33 - 25}{30} = \frac{8^{(2} }{30} = \frac{4}{15}$
