$$\left(5x^{7}y^{6}z^{5}\right)^{2}$$

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

$$5^{2}\left(x^{7}\right)^{2}\left(y^{6}\right)^{2}\left(z^{5}\right)^{2}$$

Codi 5 i'r pŵer 2.

$$25\left(x^{7}\right)^{2}\left(y^{6}\right)^{2}\left(z^{5}\right)^{2}$$

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

$$25x^{7\times 2}y^{6\times 2}z^{5\times 2}$$

Lluoswch 7 â 2.
