Enrhifo

$$\frac{1}{5000000000000}=2 \cdot 10^{-13}$$

Camau Ateb

Er mwyn lluosi pwerau sy’n rhannu’r un sail, adiwch eu esbonyddion. Adiwch 1 a -14 i gael -13.

$$\frac{10^{-13}}{50\times 10^{-2}}$$

Er mwyn rhannu pwerau sy’n rhannu’r un sail, tynnwch esbonydd yr enwadur o esbonydd y rhifiadur.

$$\frac{1}{50\times 10^{11}}$$

Cyfrifo 10 i bŵer 11 a chael 100000000000.

$$\frac{1}{50\times 100000000000}$$

Lluosi 50 a 100000000000 i gael 5000000000000.

$$\frac{1}{5000000000000}$$

Ffactor

$$\frac{1}{2 ^ {12} \cdot 5 ^ {13}} = 2 \times 10^{-13}$$
