Passi tas-Soluzzjonijiet

Ikkalkula \frac{3}{2} bil-power ta' 2 u tikseb \frac{9}{4}.

$$\frac{7}{4}-\sqrt[3]{\frac{9}{4}+2^{-1}+1}$$

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

$$\frac{7}{4}-\sqrt[3]{\frac{9}{4}+\frac{1}{2}+1}$$

Żid \frac{9}{4} u \frac{1}{2} biex tikseb \frac{11}{4}.

$$\frac{7}{4}-\sqrt[3]{\frac{11}{4}+1}$$

Żid \frac{11}{4} u 1 biex tikseb \frac{15}{4}.

$$\frac{7}{4}-\sqrt[3]{\frac{15}{4}}$$

Fattur

$$\frac{7 - 2 \sqrt[3]{30}}{4} = 0.1963837470230707$$
