Passi tas-Soluzzjonijiet

Biex timmultiplika l-qawwa tal-istess bażi, żid l-esponenti tagħhom. Żid 9 u -6 biex tikseb 3.

$$\frac{9\times 10^{3}\times 45\times 5\times 10^{-6}}{\left(15\times 10^{-2}\right)^{2}}$$

Biex timmultiplika l-qawwa tal-istess bażi, żid l-esponenti tagħhom. Żid 3 u -6 biex tikseb -3.

$$\frac{9\times 10^{-3}\times 45\times 5}{\left(15\times 10^{-2}\right)^{2}}$$

Ikkalkula 10 bil-power ta' -3 u tikseb \frac{1}{1000}.

$$\frac{9\times \frac{1}{1000}\times 45\times 5}{\left(15\times 10^{-2}\right)^{2}}$$

Immultiplika 9 u \frac{1}{1000} biex tikseb \frac{9}{1000}.

$$\frac{\frac{9}{1000}\times 45\times 5}{\left(15\times 10^{-2}\right)^{2}}$$

Immultiplika \frac{9}{1000} u 45 biex tikseb \frac{81}{200}.

$$\frac{\frac{81}{200}\times 5}{\left(15\times 10^{-2}\right)^{2}}$$

Immultiplika \frac{81}{200} u 5 biex tikseb \frac{81}{40}.

$$\frac{\frac{81}{40}}{\left(15\times 10^{-2}\right)^{2}}$$

Ikkalkula 10 bil-power ta' -2 u tikseb \frac{1}{100}.

$$\frac{\frac{81}{40}}{\left(15\times \frac{1}{100}\right)^{2}}$$

Immultiplika 15 u \frac{1}{100} biex tikseb \frac{3}{20}.

$$\frac{\frac{81}{40}}{\left(\frac{3}{20}\right)^{2}}$$

Ikkalkula \frac{3}{20} bil-power ta' 2 u tikseb \frac{9}{400}.

$$\frac{\frac{81}{40}}{\frac{9}{400}}$$

Iddividi \frac{81}{40} b'\frac{9}{400} billi timmultiplika \frac{81}{40} bir-reċiproku ta' \frac{9}{400}.

$$\frac{81}{40}\times \frac{400}{9}$$

Immultiplika \frac{81}{40} u \frac{400}{9} biex tikseb 90.
