Camau Ateb

Er mwyn lluosi pwerau sy’n rhannu’r un sail, adiwch eu esbonyddion. Adiwch -3 a -6 i gael -9.

$$\frac{1}{500\times 10^{-9}\times 25}$$

Cyfrifo 10 i bŵer -9 a chael \frac{1}{1000000000}.

$$\frac{1}{500\times \frac{1}{1000000000}\times 25}$$

Lluosi 500 a \frac{1}{1000000000} i gael \frac{1}{2000000}.

$$\frac{1}{\frac{1}{2000000}\times 25}$$

Lluosi \frac{1}{2000000} a 25 i gael \frac{1}{80000}.

$$\frac{1}{\frac{1}{80000}}$$

Rhannwch 1 â \frac{1}{80000} drwy luosi 1 â chilydd \frac{1}{80000}.

$$1\times 80000$$

Lluosi 1 a 80000 i gael 80000.

$$80000$$

Ffactor

$$2^{7}\times 5^{4}$$
