Ngā Upane Otinga

Whakakorea atu te tauwehe pūnoa nui rawa 9 i roto i te 81 me te 9.

$$-9\sqrt{3}+\frac{2}{3}\sqrt{3}\left(-9\right)+3\sqrt{3}$$

Tuhia te \frac{2}{3}\left(-9\right) hei hautanga kotahi.

$$-9\sqrt{3}+\frac{2\left(-9\right)}{3}\sqrt{3}+3\sqrt{3}$$

Whakareatia te 2 ki te -9, ka -18.

$$-9\sqrt{3}+\frac{-18}{3}\sqrt{3}+3\sqrt{3}$$

Whakawehea te -18 ki te 3, kia riro ko -6.

$$-9\sqrt{3}-6\sqrt{3}+3\sqrt{3}$$

Pahekotia te -9\sqrt{3} me -6\sqrt{3}, ka -15\sqrt{3}.

$$-15\sqrt{3}+3\sqrt{3}$$

Pahekotia te -15\sqrt{3} me 3\sqrt{3}, ka -12\sqrt{3}.

$$-12\sqrt{3}$$
