Camau Ateb

Defnyddio rheolau esbonyddion i symleiddio’r mynegiad.

$$\left(-4x^{4}y^{5}\right)^{2}$$

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

$$\left(-4\right)^{2}\left(x^{4}\right)^{2}\left(y^{5}\right)^{2}$$

Codi -4 i'r pŵer 2.

$$16\left(x^{4}\right)^{2}\left(y^{5}\right)^{2}$$

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

$$16x^{4\times 2}y^{5\times 2}$$

Lluoswch 4 â 2.

$$16x^{8}y^{5\times 2}$$

Lluoswch 5 â 2.

$$16x^{8}y^{10}$$
