Camau Ateb

I godi pŵer rhif i bŵer arall, lluoswch yr esbonyddion. Lluoswch -3 a 0 i gael 0.

$$\frac{1}{2}\times 216^{\frac{2}{3}}+5.27^{0}-81^{0.75}\times 0.5^{-1}$$

Cyfrifo 216 i bŵer \frac{2}{3} a chael 36.

$$\frac{1}{2}\times 36+5.27^{0}-81^{0.75}\times 0.5^{-1}$$

Lluosi \frac{1}{2} a 36 i gael 18.

$$18+5.27^{0}-81^{0.75}\times 0.5^{-1}$$

Cyfrifo 5.27 i bŵer 0 a chael 1.

$$18+1-81^{0.75}\times 0.5^{-1}$$

Adio 18 a 1 i gael 19.

$$19-81^{0.75}\times 0.5^{-1}$$

Cyfrifo 81 i bŵer 0.75 a chael 27.

$$19-27\times 0.5^{-1}$$

Cyfrifo 0.5 i bŵer -1 a chael 2.

$$19-27\times 2$$

Lluosi 27 a 2 i gael 54.

$$19-54$$

Tynnu 54 o 19 i gael -35.
