Camau Ateb

I godi pŵer rhif i bŵer arall, lluoswch yr esbonyddion. Lluoswch -4 a 2 i gael -8.

$$34\times 5^{2}+6\times 5^{-8}$$

Cyfrifo 5 i bŵer 2 a chael 25.

$$34\times 25+6\times 5^{-8}$$

Lluosi 34 a 25 i gael 850.

$$850+6\times 5^{-8}$$

Cyfrifo 5 i bŵer -8 a chael \frac{1}{390625}.

$$850+6\times \frac{1}{390625}$$

Lluosi 6 a \frac{1}{390625} i gael \frac{6}{390625}.

$$850+\frac{6}{390625}$$

Adio 850 a \frac{6}{390625} i gael \frac{332031256}{390625}.

$$\frac{332031256}{390625}$$

Ffactor

$$\frac{2 ^ {3} \cdot 1493 \cdot 27799}{5 ^ {8}} = 850\frac{6}{390625} = 850.00001536$$
