Passi tas-Soluzzjonijiet

Ikkalkula -5 bil-power ta' 2 u tikseb 25.

$$\frac{25-3^{2}+\left(\frac{2}{3}\right)^{0}}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

Ikkalkula 3 bil-power ta' 2 u tikseb 9.

$$\frac{25-9+\left(\frac{2}{3}\right)^{0}}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

Naqqas 9 minn 25 biex tikseb 16.

$$\frac{16+\left(\frac{2}{3}\right)^{0}}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

Ikkalkula \frac{2}{3} bil-power ta' 0 u tikseb 1.

$$\frac{16+1}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

Żid 16 u 1 biex tikseb 17.

$$\frac{17}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

Ikkalkula 3 bil-power ta' -2 u tikseb \frac{1}{9}.

$$\frac{17}{\frac{1}{9}+\frac{1}{5}+\frac{1}{2}}$$

Żid \frac{1}{9} u \frac{1}{5} biex tikseb \frac{14}{45}.

$$\frac{17}{\frac{14}{45}+\frac{1}{2}}$$

Żid \frac{14}{45} u \frac{1}{2} biex tikseb \frac{73}{90}.

$$\frac{17}{\frac{73}{90}}$$

Iddividi 17 b'\frac{73}{90} billi timmultiplika 17 bir-reċiproku ta' \frac{73}{90}.

$$17\times \frac{90}{73}$$

Immultiplika 17 u \frac{90}{73} biex tikseb \frac{1530}{73}.

$$\frac{1530}{73}$$

Fattur

$$\frac{2 \cdot 3 ^ {2} \cdot 5 \cdot 17}{73} = 20\frac{70}{73} = 20.958904109589042$$
