Datrys 1/alphabeta+1/betagamma+1/gammaalpha=

$$\frac { 1 } { \alpha \beta } + \frac { 1 } { \beta \gamma } + \frac { 1 } { \gamma \alpha } =$$

Enrhifo

$$\frac{\alpha +\beta +\gamma }{\alpha \beta \gamma }$$

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin \alpha \beta a \beta \gamma yw \alpha \beta \gamma . Lluoswch \frac{1}{\alpha \beta } â \frac{\gamma }{\gamma }. Lluoswch \frac{1}{\beta \gamma } â \frac{\alpha }{\alpha }.

$$\frac{\gamma }{\alpha \beta \gamma }+\frac{\alpha }{\alpha \beta \gamma }+\frac{1}{\gamma \alpha }$$

Gan fod gan \frac{\gamma }{\alpha \beta \gamma } a \frac{\alpha }{\alpha \beta \gamma } yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.
