Passi tas-Soluzzjonijiet

Naqqas il-frazzjoni \frac{2}{20} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 2.

$$\left(\frac{1}{10}\right)^{4}\times 3+\left(\frac{9}{25}\right)^{3}\times \frac{1}{10}\times 3$$

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

$$\frac{1}{10000}\times 3+\left(\frac{9}{25}\right)^{3}\times \frac{1}{10}\times 3$$

Immultiplika \frac{1}{10000} u 3 biex tikseb \frac{3}{10000}.

$$\frac{3}{10000}+\left(\frac{9}{25}\right)^{3}\times \frac{1}{10}\times 3$$

Ikkalkula \frac{9}{25} bil-power ta' 3 u tikseb \frac{729}{15625}.

$$\frac{3}{10000}+\frac{729}{15625}\times \frac{1}{10}\times 3$$

Immultiplika \frac{729}{15625} u \frac{1}{10} biex tikseb \frac{729}{156250}.

$$\frac{3}{10000}+\frac{729}{156250}\times 3$$

Immultiplika \frac{729}{156250} u 3 biex tikseb \frac{2187}{156250}.

$$\frac{3}{10000}+\frac{2187}{156250}$$

Żid \frac{3}{10000} u \frac{2187}{156250} biex tikseb \frac{17871}{1250000}.

$$\frac{17871}{1250000}$$

Fattur

$$\frac{3 \cdot 7 \cdot 23 \cdot 37}{2 ^ {4} \cdot 5 ^ {7}} = 0.0142968$$
