Evalwa

$$\frac{2}{9}\approx 0.222222222$$

Passi tas-Soluzzjonijiet

Ikkalkula \frac{2}{3} bil-power ta' 3 u tikseb \frac{8}{27}.

$$\frac{8}{27}-\frac{1}{9}\sqrt[3]{\frac{8}{27}}$$

Ikkalkola \sqrt[3]{\frac{8}{27}} u ikseb \frac{2}{3}.

$$\frac{8}{27}-\frac{1}{9}\times \frac{2}{3}$$

Immultiplika -\frac{1}{9} u \frac{2}{3} biex tikseb -\frac{2}{27}.

$$\frac{8}{27}-\frac{2}{27}$$

Naqqas \frac{2}{27} minn \frac{8}{27} biex tikseb \frac{2}{9}.

$$\frac{2}{9}$$

Fattur

$$\frac{2}{3 ^ {2}} = 0.2222222222222222$$
