\sqrt{64+\left(-1-7\right)^{2}}
Tātaihia te -8 mā te pū o 2, kia riro ko 64.
\sqrt{64+\left(-8\right)^{2}}
Tangohia te 7 i te -1, ka -8.
\sqrt{64+64}
Tātaihia te -8 mā te pū o 2, kia riro ko 64.
\sqrt{128}
Tāpirihia te 64 ki te 64, ka 128.
8\sqrt{2}
Tauwehea te 128=8^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{8^{2}\times 2} hei hua o ngā pūtake rua \sqrt{8^{2}}\sqrt{2}. Tuhia te pūtakerua o te 8^{2}.
