Passi tas-Soluzzjonijiet

Biex timmultiplika l-qawwa tal-istess bażi, żid l-esponenti tagħhom. Żid 8 u -12 biex tikseb -4.

$$138\times 10^{-4}\times 54$$

Ikkalkula 10 bil-power ta' -4 u tikseb \frac{1}{10000}.

$$138\times \frac{1}{10000}\times 54$$

Immultiplika 138 u \frac{1}{10000} biex tikseb \frac{69}{5000}.

$$\frac{69}{5000}\times 54$$

Immultiplika \frac{69}{5000} u 54 biex tikseb \frac{1863}{2500}.

$$\frac{1863}{2500}$$

Fattur

$$\frac{3 ^ {4} \cdot 23}{2 ^ {2} \cdot 5 ^ {4}} = 0.7452$$
