Iffattura 8=2^{2}\times 2. Erġa' ikteb l-għerq kwadrat tal-prodott \sqrt{2^{2}\times 2} bħala l-prodott tal-għeruq kwadrati \sqrt{2^{2}}\sqrt{2}. Ħu l-għerq kwadrat ta' 2^{2}.

$$\left(3\times 2\sqrt{2}\right)^{2}$$

Immultiplika 3 u 2 biex tikseb 6.

$$\left(6\sqrt{2}\right)^{2}$$

Espandi \left(6\sqrt{2}\right)^{2}.

$$6^{2}\left(\sqrt{2}\right)^{2}$$

Ikkalkula 6 bil-power ta' 2 u tikseb 36.

$$36\left(\sqrt{2}\right)^{2}$$

Il-kwadrat ta' \sqrt{2} huwa 2.

$$36\times 2$$

Immultiplika 36 u 2 biex tikseb 72.
