Ngā Upane Otinga

Tātaihia te -\frac{3}{5} mā te pū o 3, kia riro ko -\frac{27}{125}.

$$-\frac{27}{125}\times \left(\frac{25}{9}\right)^{2}\left(-\frac{2}{3}\right)^{2}$$

Tātaihia te \frac{25}{9} mā te pū o 2, kia riro ko \frac{625}{81}.

$$-\frac{27}{125}\times \frac{625}{81}\left(-\frac{2}{3}\right)^{2}$$

Me whakarea te -\frac{27}{125} ki te \frac{625}{81} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-27\times 625}{125\times 81}\left(-\frac{2}{3}\right)^{2}$$

Mahia ngā whakarea i roto i te hautanga \frac{-27\times 625}{125\times 81}.

$$\frac{-16875}{10125}\left(-\frac{2}{3}\right)^{2}$$

Whakahekea te hautanga \frac{-16875}{10125} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3375.

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

Tātaihia te -\frac{2}{3} mā te pū o 2, kia riro ko \frac{4}{9}.

$$-\frac{5}{3}\times \frac{4}{9}$$

Me whakarea te -\frac{5}{3} ki te \frac{4}{9} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-5\times 4}{3\times 9}$$

Mahia ngā whakarea i roto i te hautanga \frac{-5\times 4}{3\times 9}.

$$\frac{-20}{27}$$

Ka taea te hautanga \frac{-20}{27} te tuhi anō ko -\frac{20}{27} mā te tango i te tohu tōraro.

$$-\frac{20}{27}$$

Tauwehe
