Datrys (ab^-1n^-2)^2

$$( a b ^ { - 1 } n ^ { - 2 } ) ^ { 2 }$$

Enrhifo

$$\frac{\left(\frac{a}{b}\right)^{2}}{n^{4}}$$

Camau ar gyfer Codi Cynnyrch i Bŵer

Defnyddio rheolau esbonyddion i symleiddio’r mynegiad.

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

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

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

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

$$a^{2}b^{-2}n^{-2\times 2}$$

Lluoswch -1 â 2.

$$a^{2}\times \frac{1}{b^{2}}n^{-2\times 2}$$

Lluoswch -2 â 2.

$$a^{2}\times \frac{1}{b^{2}}\times \frac{1}{n^{4}}$$
