Camau Ateb

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

$$j=\left(-2+4i\right)\left(-\frac{1}{10}-\frac{1}{5}i\right)$$

Lluosi -2+4i a -\frac{1}{10}-\frac{1}{5}i i gael 1.

$$j=1$$

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

$$l=1$$

Ystyriwch yr hafaliad (6). Mewnosod y gwerthoedd sy’n hysbys i’r hafaliad.

$$n=1$$

Mae’r system wedi’i datrys nawr.

$$a=-\frac{1}{10}-\frac{1}{5}i j=1 k=28-96i l=1 m=28-96i n=1 o=28-96i$$
