Passi tas-Soluzzjonijiet

Ikkalkula 2 bil-power ta' 2 u tikseb 4.

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

Ikkalkula -2 bil-power ta' 3 u tikseb -8.

$$|-4-8-2^{-1}+\left(-2\right)^{-2}|$$

Naqqas 8 minn -4 biex tikseb -12.

$$|-12-2^{-1}+\left(-2\right)^{-2}|$$

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

$$|-12-\frac{1}{2}+\left(-2\right)^{-2}|$$

Naqqas \frac{1}{2} minn -12 biex tikseb -\frac{25}{2}.

$$|-\frac{25}{2}+\left(-2\right)^{-2}|$$

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

$$|-\frac{25}{2}+\frac{1}{4}|$$

Żid -\frac{25}{2} u \frac{1}{4} biex tikseb -\frac{49}{4}.

$$|-\frac{49}{4}|$$

Il-valur assolut ta' numru reali a huwa a meta a\geq 0, jew -a meta a<0. Il-valur assolut ta' -\frac{49}{4} huwa \frac{49}{4}.

$$\frac{49}{4}$$

Fattur

$$\frac{7 ^ {2}}{2 ^ {2}} = 12\frac{1}{4} = 12.25$$
