Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 2 me te 5 kia riro ai te 7.

$$\left(\frac{1}{2}\right)^{7}\left(-\frac{1}{2}\right)^{3}$$

Tātaihia te \frac{1}{2} mā te pū o 7, kia riro ko \frac{1}{128}.

$$\frac{1}{128}\left(-\frac{1}{2}\right)^{3}$$

Tātaihia te -\frac{1}{2} mā te pū o 3, kia riro ko -\frac{1}{8}.

$$\frac{1}{128}\left(-\frac{1}{8}\right)$$

Me whakarea te \frac{1}{128} ki te -\frac{1}{8} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{1\left(-1\right)}{128\times 8}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\left(-1\right)}{128\times 8}.

$$\frac{-1}{1024}$$

Ka taea te hautanga \frac{-1}{1024} te tuhi anō ko -\frac{1}{1024} mā te tango i te tohu tōraro.

$$-\frac{1}{1024}$$

Tauwehe

$$-\frac{1}{1024} = -0.0009765625$$
