Datrys (1/3x^-3y)^2

$$( \frac { 1 } { 3 } x ^ { - 3 } y ) ^ { 2 }$$

Enrhifo

$$\frac{y^{2}}{9x^{6}}$$

Camau Ateb

Defnyddio rheolau esbonyddion i symleiddio’r mynegiad.

$$\left(\frac{1}{3}x^{-3}y^{1}\right)^{2}$$

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

$$\left(\frac{1}{3}\right)^{2}\left(x^{-3}\right)^{2}\left(y^{1}\right)^{2}$$

Codi \frac{1}{3} i'r pŵer 2.

$$\frac{1}{9}\left(x^{-3}\right)^{2}\left(y^{1}\right)^{2}$$

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

$$\frac{1}{9}x^{-3\times 2}y^{2}$$

Lluoswch -3 â 2.

$$\frac{1}{9}\times \frac{1}{x^{6}}y^{2}$$
