Atrisinājuma darbības

Vienādot daļskaitli \frac{3}{9} līdz mazākajam loceklim, izvelkot un saīsinot 3.

$$\left(\frac{\left(\frac{2\times \frac{1}{3}}{3}\right)^{-2}}{\left(\frac{9}{4}\right)^{2}\times \left(\frac{2}{5}\right)^{-1}}\right)^{-1}$$

Reiziniet 2 un \frac{1}{3}, lai iegūtu \frac{2}{3}.

$$\left(\frac{\left(\frac{\frac{2}{3}}{3}\right)^{-2}}{\left(\frac{9}{4}\right)^{2}\times \left(\frac{2}{5}\right)^{-1}}\right)^{-1}$$

Izsakiet \frac{\frac{2}{3}}{3} kā vienu daļskaitli.

$$\left(\frac{\left(\frac{2}{3\times 3}\right)^{-2}}{\left(\frac{9}{4}\right)^{2}\times \left(\frac{2}{5}\right)^{-1}}\right)^{-1}$$

Reiziniet 3 un 3, lai iegūtu 9.

$$\left(\frac{\left(\frac{2}{9}\right)^{-2}}{\left(\frac{9}{4}\right)^{2}\times \left(\frac{2}{5}\right)^{-1}}\right)^{-1}$$

Aprēķiniet \frac{2}{9} pakāpē -2 un iegūstiet \frac{81}{4}.

$$\left(\frac{\frac{81}{4}}{\left(\frac{9}{4}\right)^{2}\times \left(\frac{2}{5}\right)^{-1}}\right)^{-1}$$

Aprēķiniet \frac{9}{4} pakāpē 2 un iegūstiet \frac{81}{16}.

$$\left(\frac{\frac{81}{4}}{\frac{81}{16}\times \left(\frac{2}{5}\right)^{-1}}\right)^{-1}$$

Aprēķiniet \frac{2}{5} pakāpē -1 un iegūstiet \frac{5}{2}.

$$\left(\frac{\frac{81}{4}}{\frac{81}{16}\times \frac{5}{2}}\right)^{-1}$$

Reiziniet \frac{81}{16} un \frac{5}{2}, lai iegūtu \frac{405}{32}.

$$\left(\frac{\frac{81}{4}}{\frac{405}{32}}\right)^{-1}$$

Daliet \frac{81}{4} ar \frac{405}{32}, reizinot \frac{81}{4} ar apgriezto daļskaitli \frac{405}{32} .

$$\left(\frac{81}{4}\times \frac{32}{405}\right)^{-1}$$

Reiziniet \frac{81}{4} un \frac{32}{405}, lai iegūtu \frac{8}{5}.

$$\left(\frac{8}{5}\right)^{-1}$$

Aprēķiniet \frac{8}{5} pakāpē -1 un iegūstiet \frac{5}{8}.

$$\frac{5}{8}$$
