$$\left(0.2x^{4}y^{3}\right)^{2}$$

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

$$0.2^{2}\left(x^{4}\right)^{2}\left(y^{3}\right)^{2}$$

Codi 0.2 i'r pŵer 2.

$$0.04\left(x^{4}\right)^{2}\left(y^{3}\right)^{2}$$

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

$$0.04x^{4\times 2}y^{3\times 2}$$

Lluoswch 4 â 2.

$$0.04x^{8}y^{3\times 2}$$

Lluoswch 3 â 2.

$$0.04x^{8}y^{6}$$
