Camau Ateb

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

$$828\times 10^{-9}\times 2$$

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

$$828\times \frac{1}{1000000000}\times 2$$

Lluosi 828 a \frac{1}{1000000000} i gael \frac{207}{250000000}.

$$\frac{207}{250000000}\times 2$$

Lluosi \frac{207}{250000000} a 2 i gael \frac{207}{125000000}.

$$\frac{207}{125000000}$$

Ffactor

$$\frac{3 ^ {2} \cdot 23}{2 ^ {6} \cdot 5 ^ {9}} = 1.656 \times 10^{-6}$$
