Camau Ateb

Ffactora 4=2\times 2. Ailysgrifennu ail isradd y lluoswm \sqrt{2\times 2} fel lluoswm ail israddau \sqrt{2}\sqrt{2}.

$$\sqrt{2}\sqrt{2}\sqrt{2}+4-\frac{2}{6}$$

Lluosi \sqrt{2} a \sqrt{2} i gael 2.

$$2\sqrt{2}+4-\frac{2}{6}$$

Lleihau'r ffracsiwn \frac{2}{6} i'r graddau lleiaf posib drwy dynnu a chanslo allan 2.

$$2\sqrt{2}+4-\frac{1}{3}$$

Troswch y rhif degol 4 i’r ffracsiwn \frac{12}{3}.

$$2\sqrt{2}+\frac{12}{3}-\frac{1}{3}$$

Gan fod gan \frac{12}{3} a \frac{1}{3} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.

$$2\sqrt{2}+\frac{12-1}{3}$$

Tynnu 1 o 12 i gael 11.

$$2\sqrt{2}+\frac{11}{3}$$

Ffactor

$$\frac{6 \sqrt{2} + 11}{3} = 6.495093791412857$$
