Atrisinājuma darbības

Reiziniet 0 un 5, lai iegūtu 0.

$$\left(0^{2}-\frac{\frac{1}{36}}{\left(-\frac{1}{3}\right)^{3}}\right)\times \frac{2}{3}-\frac{\left(\frac{1}{3}\right)^{2}}{25}\times 15$$

Aprēķiniet 0 pakāpē 2 un iegūstiet 0.

$$\left(0-\frac{\frac{1}{36}}{\left(-\frac{1}{3}\right)^{3}}\right)\times \frac{2}{3}-\frac{\left(\frac{1}{3}\right)^{2}}{25}\times 15$$

Aprēķiniet -\frac{1}{3} pakāpē 3 un iegūstiet -\frac{1}{27}.

$$\left(0-\frac{\frac{1}{36}}{-\frac{1}{27}}\right)\times \frac{2}{3}-\frac{\left(\frac{1}{3}\right)^{2}}{25}\times 15$$

Daliet \frac{1}{36} ar -\frac{1}{27}, reizinot \frac{1}{36} ar apgriezto daļskaitli -\frac{1}{27} .

$$\left(0-\frac{1}{36}\left(-27\right)\right)\times \frac{2}{3}-\frac{\left(\frac{1}{3}\right)^{2}}{25}\times 15$$

Reiziniet \frac{1}{36} un -27, lai iegūtu -\frac{3}{4}.

$$\left(0-\left(-\frac{3}{4}\right)\right)\times \frac{2}{3}-\frac{\left(\frac{1}{3}\right)^{2}}{25}\times 15$$

Skaitļa -\frac{3}{4} pretstats ir \frac{3}{4}.

$$\left(0+\frac{3}{4}\right)\times \frac{2}{3}-\frac{\left(\frac{1}{3}\right)^{2}}{25}\times 15$$

Saskaitiet 0 un \frac{3}{4}, lai iegūtu \frac{3}{4}.

$$\frac{3}{4}\times \frac{2}{3}-\frac{\left(\frac{1}{3}\right)^{2}}{25}\times 15$$

Reiziniet \frac{3}{4} un \frac{2}{3}, lai iegūtu \frac{1}{2}.

$$\frac{1}{2}-\frac{\left(\frac{1}{3}\right)^{2}}{25}\times 15$$

Aprēķiniet \frac{1}{3} pakāpē 2 un iegūstiet \frac{1}{9}.

$$\frac{1}{2}-\frac{\frac{1}{9}}{25}\times 15$$

Izsakiet \frac{\frac{1}{9}}{25} kā vienu daļskaitli.

$$\frac{1}{2}-\frac{1}{9\times 25}\times 15$$

Reiziniet 9 un 25, lai iegūtu 225.

$$\frac{1}{2}-\frac{1}{225}\times 15$$

Reiziniet \frac{1}{225} un 15, lai iegūtu \frac{1}{15}.

$$\frac{1}{2}-\frac{1}{15}$$

Atņemiet \frac{1}{15} no \frac{1}{2}, lai iegūtu \frac{13}{30}.

$$\frac{13}{30}$$

Sadalīt reizinātājos

$$\frac{13}{2 \cdot 3 \cdot 5} = 0,43333333333333335$$
