Passi tas-Soluzzjonijiet

Ikkalkola \sqrt[4]{\frac{1}{81}} u ikseb \frac{1}{3}.

$$\frac{1}{3}+\left(\frac{2}{3}\right)^{-1}-0.002\times 10^{3}$$

Ikkalkula \frac{2}{3} bil-power ta' -1 u tikseb \frac{3}{2}.

$$\frac{1}{3}+\frac{3}{2}-0.002\times 10^{3}$$

Żid \frac{1}{3} u \frac{3}{2} biex tikseb \frac{11}{6}.

$$\frac{11}{6}-0.002\times 10^{3}$$

Ikkalkula 10 bil-power ta' 3 u tikseb 1000.

$$\frac{11}{6}-0.002\times 1000$$

Immultiplika 0.002 u 1000 biex tikseb 2.

$$\frac{11}{6}-2$$

Naqqas 2 minn \frac{11}{6} biex tikseb -\frac{1}{6}.

$$-\frac{1}{6}$$

Fattur

$$-\frac{1}{6} = -0.16666666666666666$$
