Passi tas-Soluzzjonijiet

Immultiplika 11 u 1 biex tikseb 11.

$$\frac{11-3\times 3}{\left(1+0.2\right)^{3}}\times 30$$

Immultiplika 3 u 3 biex tikseb 9.

$$\frac{11-9}{\left(1+0.2\right)^{3}}\times 30$$

Naqqas 9 minn 11 biex tikseb 2.

$$\frac{2}{\left(1+0.2\right)^{3}}\times 30$$

Żid 1 u 0.2 biex tikseb 1.2.

$$\frac{2}{1.2^{3}}\times 30$$

Ikkalkula 1.2 bil-power ta' 3 u tikseb 1.728.

$$\frac{2}{1.728}\times 30$$

Espandi \frac{2}{1.728} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'1000.

$$\frac{2000}{1728}\times 30$$

Naqqas il-frazzjoni \frac{2000}{1728} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 16.

$$\frac{125}{108}\times 30$$

Immultiplika \frac{125}{108} u 30 biex tikseb \frac{625}{18}.

$$\frac{625}{18}$$

Fattur

$$\frac{5 ^ {4}}{2 \cdot 3 ^ {2}} = 34\frac{13}{18} = 34.72222222222222$$
