Explicație pas cu pas:
[tex] \frac{5}{14} + \frac{3}{8} \times \frac{16}{21} \\ \\ \frac{5}{14} + \frac{1}{1} \times \frac{2}{7} \\ \frac{5}{14} + \frac{2}{7} \\ \: \\ \\ \frac{5 + 4}{14} [/tex]
Am simplificat apoi am ridicat la putere si gata
ultimul
[tex]2 - \frac{7}{8 } \times {1} \frac{1}{7} \\ \\ 2 - \frac{7}{8} \times \frac{7 \times 1 + 1}{7} = 2 - \frac{7}{8} \times \frac{8}{7} = 2[/tex]
aici am simplificat la final
