$$2.18\times \frac{1}{1000000000000000000}x=\frac{6.63\times 10^{-26}\times 3}{434\times 10^{-9}}$$

Lluosi 2.18 a \frac{1}{1000000000000000000} i gael \frac{109}{50000000000000000000}.

$$\frac{109}{50000000000000000000}x=\frac{6.63\times 10^{-26}\times 3}{434\times 10^{-9}}$$

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

$$\frac{109}{50000000000000000000}x=\frac{3\times 6.63}{434\times 10^{17}}$$

Lluosi 3 a 6.63 i gael 19.89.

$$\frac{109}{50000000000000000000}x=\frac{19.89}{434\times 10^{17}}$$

Cyfrifo 10 i bŵer 17 a chael 100000000000000000.

$$\frac{109}{50000000000000000000}x=\frac{19.89}{434\times 100000000000000000}$$

Lluosi 434 a 100000000000000000 i gael 43400000000000000000.

$$\frac{109}{50000000000000000000}x=\frac{19.89}{43400000000000000000}$$

Ehangu \frac{19.89}{43400000000000000000} drwy luosi'r rhifiadur a'r enwadur gyda 100.

$$\frac{109}{50000000000000000000}x=\frac{1989}{4340000000000000000000}$$

Lluoswch y ddwy ochr â \frac{50000000000000000000}{109}, cilyddol \frac{109}{50000000000000000000}.

$$x=\frac{1989}{4340000000000000000000}\times \frac{50000000000000000000}{109}$$

Lluosi \frac{1989}{4340000000000000000000} a \frac{50000000000000000000}{109} i gael \frac{9945}{47306}.
