Ffactora 12=2^{2}\times 3. Ailysgrifennu ail isradd y lluoswm \sqrt{2^{2}\times 3} fel lluoswm ail israddau \sqrt{2^{2}}\sqrt{3}. Cymryd isradd 2^{2}.

$$3\times 2\sqrt{3}\sqrt{18}$$

Lluosi 3 a 2 i gael 6.

$$6\sqrt{3}\sqrt{18}$$

Ffactora 18=3^{2}\times 2. Ailysgrifennu ail isradd y lluoswm \sqrt{3^{2}\times 2} fel lluoswm ail israddau \sqrt{3^{2}}\sqrt{2}. Cymryd isradd 3^{2}.

$$6\sqrt{3}\times 3\sqrt{2}$$

Lluosi 6 a 3 i gael 18.

$$18\sqrt{3}\sqrt{2}$$

I luosi \sqrt{3} a \sqrt{2}, dylid lluosi'r rhifau dan yr ail isradd.

$$18\sqrt{6}$$
