Passi tas-Soluzzjonijiet

Ikkalkula 12 bil-power ta' 2 u tikseb 144.

$$\sqrt{144-16^{2}}$$

Ikkalkula 16 bil-power ta' 2 u tikseb 256.

$$\sqrt{144-256}$$

Naqqas 256 minn 144 biex tikseb -112.

$$\sqrt{-112}$$

Iffattura -112=\left(4i\right)^{2}\times 7. Erġa' ikteb l-għerq kwadrat tal-prodott \sqrt{\left(4i\right)^{2}\times 7} bħala l-prodott tal-għeruq kwadrati \sqrt{\left(4i\right)^{2}}\sqrt{7}. Ħu l-għerq kwadrat ta' \left(4i\right)^{2}.
