Passi tas-Soluzzjonijiet

Ikkalkula 0.5 bil-power ta' 2 u tikseb 0.25.

$$-0.25+\frac{1}{4}-|-2^{2}-4|-\left(-\frac{1\times 2+1}{2}\right)^{3}\times \frac{4}{9}$$

Żid -0.25 u \frac{1}{4} biex tikseb 0.

$$0-|-2^{2}-4|-\left(-\frac{1\times 2+1}{2}\right)^{3}\times \frac{4}{9}$$

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

$$0-|-4-4|-\left(-\frac{1\times 2+1}{2}\right)^{3}\times \frac{4}{9}$$

Naqqas 4 minn -4 biex tikseb -8.

$$0-|-8|-\left(-\frac{1\times 2+1}{2}\right)^{3}\times \frac{4}{9}$$

Il-valur assolut ta' numru reali a huwa a meta a\geq 0, jew -a meta a<0. Il-valur assolut ta' -8 huwa 8.

$$0-8-\left(-\frac{1\times 2+1}{2}\right)^{3}\times \frac{4}{9}$$

Naqqas 8 minn 0 biex tikseb -8.

$$-8-\left(-\frac{1\times 2+1}{2}\right)^{3}\times \frac{4}{9}$$

Immultiplika 1 u 2 biex tikseb 2.

$$-8-\left(-\frac{2+1}{2}\right)^{3}\times \frac{4}{9}$$

Żid 2 u 1 biex tikseb 3.

$$-8-\left(-\frac{3}{2}\right)^{3}\times \frac{4}{9}$$

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

$$-8-\left(-\frac{27}{8}\times \frac{4}{9}\right)$$

Immultiplika -\frac{27}{8} u \frac{4}{9} biex tikseb -\frac{3}{2}.

$$-8-\left(-\frac{3}{2}\right)$$

L-oppost ta' -\frac{3}{2} huwa \frac{3}{2}.

$$-8+\frac{3}{2}$$

Żid -8 u \frac{3}{2} biex tikseb -\frac{13}{2}.

$$-\frac{13}{2}$$

Fattur
