Ngā Upane Otinga

Tātaihia te 12 mā te pū o 2, kia riro ko 144.

$$\frac{12}{\sqrt{144+8^{2}+16^{2}+8^{2}+16^{2}}}$$

Tātaihia te 8 mā te pū o 2, kia riro ko 64.

$$\frac{12}{\sqrt{144+64+16^{2}+8^{2}+16^{2}}}$$

Tāpirihia te 144 ki te 64, ka 208.

$$\frac{12}{\sqrt{208+16^{2}+8^{2}+16^{2}}}$$

Tātaihia te 16 mā te pū o 2, kia riro ko 256.

$$\frac{12}{\sqrt{208+256+8^{2}+16^{2}}}$$

Tāpirihia te 208 ki te 256, ka 464.

$$\frac{12}{\sqrt{464+8^{2}+16^{2}}}$$

Tātaihia te 8 mā te pū o 2, kia riro ko 64.

$$\frac{12}{\sqrt{464+64+16^{2}}}$$

Tāpirihia te 464 ki te 64, ka 528.

$$\frac{12}{\sqrt{528+16^{2}}}$$

Tātaihia te 16 mā te pū o 2, kia riro ko 256.

$$\frac{12}{\sqrt{528+256}}$$

Tāpirihia te 528 ki te 256, ka 784.

$$\frac{12}{\sqrt{784}}$$

Tātaitia te pūtakerua o 784 kia tae ki 28.
