I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluoswch 11775 â \frac{64}{64}.

$$\frac{11775\times 64}{64}-\frac{5\sqrt{3}}{64}$$

Gan fod gan \frac{11775\times 64}{64} a \frac{5\sqrt{3}}{64} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.

$$\frac{11775\times 64-5\sqrt{3}}{64}$$

Gwnewch y gwaith lluosi yn 11775\times 64-5\sqrt{3}.

$$\frac{753600-5\sqrt{3}}{64}$$

Ffactor

$$\frac{5 {(150720 - \sqrt{3})}}{64} = 11774.864683530659$$
