$$\left. \begin{array} { l } { k = 1 + 5 }\\ { l = {(\frac{2}{3})} ^ {k} }\\ { \text{Solve for } m \text{ where} } \\ { m = l } \end{array} \right.$$

Datrys ar gyfer k, l, m

$$m=\frac{64}{729}\approx 0.087791495$$

Camau Ateb

Ystyriwch yr hafaliad cyntaf. Adio 1 a 5 i gael 6.

$$k=6$$

Ystyriwch yr ail hafaliad. Mewnosod y gwerthoedd sy’n hysbys i’r hafaliad.

$$l=\left(\frac{2}{3}\right)^{6}$$

Cyfrifo \frac{2}{3} i bŵer 6 a chael \frac{64}{729}.

$$l=\frac{64}{729}$$

Ystyriwch y trydydd hafaliad. Mewnosod y gwerthoedd sy’n hysbys i’r hafaliad.

$$m=\frac{64}{729}$$

Mae’r system wedi’i datrys nawr.

$$k=6 l=\frac{64}{729} m=\frac{64}{729}$$
