Passi tas-Soluzzjonijiet

Naqqas 11 minn \frac{646}{125} biex tikseb -\frac{729}{125}.

$$\sqrt[3]{-\frac{729}{125}}-\sqrt{0\times 1^{-2}}+\sqrt[3]{8^{2}}$$

Ikkalkola \sqrt[3]{-\frac{729}{125}} u ikseb -\frac{9}{5}.

$$-\frac{9}{5}-\sqrt{0\times 1^{-2}}+\sqrt[3]{8^{2}}$$

Ikkalkula 1 bil-power ta' -2 u tikseb 1.

$$-\frac{9}{5}-\sqrt{0\times 1}+\sqrt[3]{8^{2}}$$

Immultiplika 0 u 1 biex tikseb 0.

$$-\frac{9}{5}-\sqrt{0}+\sqrt[3]{8^{2}}$$

Ikkalkula l-għerq kwadrat ta' 0 u ikseb 0.

$$-\frac{9}{5}-0+\sqrt[3]{8^{2}}$$

Immultiplika -1 u 0 biex tikseb 0.

$$-\frac{9}{5}+0+\sqrt[3]{8^{2}}$$

Żid -\frac{9}{5} u 0 biex tikseb -\frac{9}{5}.

$$-\frac{9}{5}+\sqrt[3]{8^{2}}$$

Ikkalkula 8 bil-power ta' 2 u tikseb 64.

$$-\frac{9}{5}+\sqrt[3]{64}$$

Ikkalkola \sqrt[3]{64} u ikseb 4.

$$-\frac{9}{5}+4$$

Żid -\frac{9}{5} u 4 biex tikseb \frac{11}{5}.

$$\frac{11}{5}$$

Fattur

$$\frac{11}{5} = 2\frac{1}{5} = 2.2$$
