Passi tas-Soluzzjonijiet

Ikkalkula \frac{2}{3} bil-power ta' -2 u tikseb \frac{9}{4}.

$$\frac{\frac{9}{4}}{6^{-1}+7^{0}}$$

Ikkalkula 6 bil-power ta' -1 u tikseb \frac{1}{6}.

$$\frac{\frac{9}{4}}{\frac{1}{6}+7^{0}}$$

Ikkalkula 7 bil-power ta' 0 u tikseb 1.

$$\frac{\frac{9}{4}}{\frac{1}{6}+1}$$

Żid \frac{1}{6} u 1 biex tikseb \frac{7}{6}.

$$\frac{\frac{9}{4}}{\frac{7}{6}}$$

Iddividi \frac{9}{4} b'\frac{7}{6} billi timmultiplika \frac{9}{4} bir-reċiproku ta' \frac{7}{6}.

$$\frac{9}{4}\times \frac{6}{7}$$

Immultiplika \frac{9}{4} u \frac{6}{7} biex tikseb \frac{27}{14}.

$$\frac{27}{14}$$

Fattur
