Datrys (8x^7/y^-7)^3

$$( \frac { 8 x ^ { 7 } } { y ^ { - 7 } } ) ^ { 3 }$$

Enrhifo

$$512\left(xy\right)^{21}$$

Camau Ateb

I godi \frac{8x^{7}}{y^{-7}} i bŵer, codwch y rhifiadur a'r enwadur i bŵer ac yna rhannwch nhw.

$$\frac{\left(8x^{7}\right)^{3}}{\left(y^{-7}\right)^{3}}$$

I godi pŵer rhif i bŵer arall, lluoswch yr esbonyddion. Lluoswch -7 a 3 i gael -21.

$$\frac{\left(8x^{7}\right)^{3}}{y^{-21}}$$

Ehangu \left(8x^{7}\right)^{3}.

$$\frac{8^{3}\left(x^{7}\right)^{3}}{y^{-21}}$$

I godi pŵer rhif i bŵer arall, lluoswch yr esbonyddion. Lluoswch 7 a 3 i gael 21.

$$\frac{8^{3}x^{21}}{y^{-21}}$$

Cyfrifo 8 i bŵer 3 a chael 512.
