Camau Ateb Byr

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluoswch -3\sqrt{3} â \frac{6}{6}.

$$\frac{\sqrt{5}}{6}+\frac{6\left(-3\right)\sqrt{3}}{6}$$

Gan fod gan \frac{\sqrt{5}}{6} a \frac{6\left(-3\right)\sqrt{3}}{6} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

$$\frac{\sqrt{5}+6\left(-3\right)\sqrt{3}}{6}$$

Gwnewch y gwaith lluosi yn \sqrt{5}+6\left(-3\right)\sqrt{3}.

$$\frac{\sqrt{5}-18\sqrt{3}}{6}$$

Ffactor

$$\frac{\sqrt{5} - 18 \sqrt{3}}{6} = -4.8234744264566665$$
