Er mwyn lluosi pwerau sy’n rhannu’r un sail, adiwch eu esbonyddion. Adiwch 4 a 3 i gael 7.

$$\frac{\left(-5\right)^{7}}{\left(-5^{2}\right)^{3}}-\frac{\left(-16\right)^{2}}{-2^{6}}-\frac{\left(-3\right)^{12}}{\left(-3^{5}\right)^{2}}$$

Cyfrifo -5 i bŵer 7 a chael -78125.

$$\frac{-78125}{\left(-5^{2}\right)^{3}}-\frac{\left(-16\right)^{2}}{-2^{6}}-\frac{\left(-3\right)^{12}}{\left(-3^{5}\right)^{2}}$$

Cyfrifo 5 i bŵer 2 a chael 25.

$$\frac{-78125}{\left(-25\right)^{3}}-\frac{\left(-16\right)^{2}}{-2^{6}}-\frac{\left(-3\right)^{12}}{\left(-3^{5}\right)^{2}}$$

Cyfrifo -25 i bŵer 3 a chael -15625.

$$\frac{-78125}{-15625}-\frac{\left(-16\right)^{2}}{-2^{6}}-\frac{\left(-3\right)^{12}}{\left(-3^{5}\right)^{2}}$$

Rhannu -78125 â -15625 i gael 5.

$$5-\frac{\left(-16\right)^{2}}{-2^{6}}-\frac{\left(-3\right)^{12}}{\left(-3^{5}\right)^{2}}$$

Cyfrifo -16 i bŵer 2 a chael 256.

$$5-\frac{256}{-2^{6}}-\frac{\left(-3\right)^{12}}{\left(-3^{5}\right)^{2}}$$

Cyfrifo 2 i bŵer 6 a chael 64.

$$5-\frac{256}{-64}-\frac{\left(-3\right)^{12}}{\left(-3^{5}\right)^{2}}$$

Rhannu 256 â -64 i gael -4.

$$5-\left(-4\right)-\frac{\left(-3\right)^{12}}{\left(-3^{5}\right)^{2}}$$

Gwrthwyneb -4 yw 4.

$$5+4-\frac{\left(-3\right)^{12}}{\left(-3^{5}\right)^{2}}$$

Adio 5 a 4 i gael 9.

$$9-\frac{\left(-3\right)^{12}}{\left(-3^{5}\right)^{2}}$$

Cyfrifo -3 i bŵer 12 a chael 531441.

$$9-\frac{531441}{\left(-3^{5}\right)^{2}}$$

Cyfrifo 3 i bŵer 5 a chael 243.

$$9-\frac{531441}{\left(-243\right)^{2}}$$

Cyfrifo -243 i bŵer 2 a chael 59049.

$$9-\frac{531441}{59049}$$

Rhannu 531441 â 59049 i gael 9.

$$9-9$$

Tynnu 9 o 9 i gael 0.
