Passi tas-Soluzzjonijiet

Immultiplika 30 u 30 biex tikseb 900.

$$\sqrt{900-12}\left(30-12\right)\left(30-15\right)$$

Naqqas 12 minn 900 biex tikseb 888.

$$\sqrt{888}\left(30-12\right)\left(30-15\right)$$

Iffattura 888=2^{2}\times 222. Erġa' ikteb l-għerq kwadrat tal-prodott \sqrt{2^{2}\times 222} bħala l-prodott tal-għeruq kwadrati \sqrt{2^{2}}\sqrt{222}. Ħu l-għerq kwadrat ta' 2^{2}.

$$2\sqrt{222}\left(30-12\right)\left(30-15\right)$$

Naqqas 12 minn 30 biex tikseb 18.

$$2\sqrt{222}\times 18\left(30-15\right)$$

Immultiplika 2 u 18 biex tikseb 36.

$$36\sqrt{222}\left(30-15\right)$$

Naqqas 15 minn 30 biex tikseb 15.

$$36\sqrt{222}\times 15$$

Immultiplika 36 u 15 biex tikseb 540.

$$540\sqrt{222}$$
