Camau Ateb

Defnyddio rheolau esbonyddion i symleiddio’r mynegiad.

$$\left(12a^{4}b^{2}\right)^{-3}$$

I godi cyfanswm dau neu fwy o rifau i bŵer, codwch bob rhif i’r pŵer a chymryd eu cyfanswm.

$$12^{-3}\left(a^{4}\right)^{-3}\left(b^{2}\right)^{-3}$$

Codi 12 i'r pŵer -3.

$$\frac{1}{1728}\left(a^{4}\right)^{-3}\left(b^{2}\right)^{-3}$$

I godi pŵer rhif i bŵer arall, lluoswch yr esbonyddion.

$$\frac{1}{1728}a^{4\left(-3\right)}b^{2\left(-3\right)}$$

Lluoswch 4 â -3.

$$\frac{1}{1728}\times \frac{1}{a^{12}}b^{2\left(-3\right)}$$

Lluoswch 2 â -3.

$$\frac{1}{1728}\times \frac{1}{a^{12}}\times \frac{1}{b^{6}}$$
