Cyfrifo 2 i bŵer 5 a chael 32.

$$32\times \frac{1}{2^{2}}=2\times 2\times 2\times 2\times 2\times \frac{1}{2\times 2}$$

Cyfrifo 2 i bŵer 2 a chael 4.

$$32\times \frac{1}{4}=2\times 2\times 2\times 2\times 2\times \frac{1}{2\times 2}$$

Lluosi 32 a \frac{1}{4} i gael \frac{32}{4}.

$$\frac{32}{4}=2\times 2\times 2\times 2\times 2\times \frac{1}{2\times 2}$$

Rhannu 32 â 4 i gael 8.

$$8=2\times 2\times 2\times 2\times 2\times \frac{1}{2\times 2}$$

Lluosi 2 a 2 i gael 4.

$$8=4\times 2\times 2\times 2\times \frac{1}{2\times 2}$$

Lluosi 4 a 2 i gael 8.

$$8=8\times 2\times 2\times \frac{1}{2\times 2}$$

Lluosi 8 a 2 i gael 16.

$$8=16\times 2\times \frac{1}{2\times 2}$$

Lluosi 16 a 2 i gael 32.

$$8=32\times \frac{1}{2\times 2}$$

Lluosi 2 a 2 i gael 4.

$$8=32\times \frac{1}{4}$$

Lluosi 32 a \frac{1}{4} i gael \frac{32}{4}.

$$8=\frac{32}{4}$$

Rhannu 32 â 4 i gael 8.

$$8=8$$
