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

Enrhifo

$$-\frac{\sqrt{6}}{4}-1\approx -1.612372436$$

Camau Ateb Byr

Cyfrifo ail isradd 4 a chael 2.

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

Rhannu 2 â 2 i gael 1.

$$-\frac{\sqrt{6}}{4}-1$$

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluoswch 1 â \frac{4}{4}.

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

Gan fod gan -\frac{\sqrt{6}}{4} a \frac{4}{4} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.

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

Ffactor

$$\frac{-\sqrt{6} - 4}{4} = -1.6123724356957945$$
