Passi tas-Soluzzjonijiet

Naqqas 1 minn \frac{1}{3} biex tikseb -\frac{2}{3}.

$$\frac{1}{2}+3\left(-\frac{2}{3}\right)^{3}+4^{-2}$$

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

$$\frac{1}{2}+3\left(-\frac{8}{27}\right)+4^{-2}$$

Immultiplika 3 u -\frac{8}{27} biex tikseb -\frac{8}{9}.

$$\frac{1}{2}-\frac{8}{9}+4^{-2}$$

Naqqas \frac{8}{9} minn \frac{1}{2} biex tikseb -\frac{7}{18}.

$$-\frac{7}{18}+4^{-2}$$

Ikkalkula 4 bil-power ta' -2 u tikseb \frac{1}{16}.

$$-\frac{7}{18}+\frac{1}{16}$$

Żid -\frac{7}{18} u \frac{1}{16} biex tikseb -\frac{47}{144}.

$$-\frac{47}{144}$$

Fattur

$$-\frac{47}{144} = -0.3263888888888889$$
