Tohaina
Kua tāruatia ki te papatopenga
a=\sqrt{49+7^{2}}
Tātaihia te 7 mā te pū o 2, kia riro ko 49.
a=\sqrt{49+49}
Tātaihia te 7 mā te pū o 2, kia riro ko 49.
a=\sqrt{98}
Tāpirihia te 49 ki te 49, ka 98.
a=7\sqrt{2}
Tauwehea te 98=7^{2}\times 2. Tuhia anō te pūtake rua o te hua \sqrt{7^{2}\times 2} hei hua o ngā pūtake rua \sqrt{7^{2}}\sqrt{2}. Tuhia te pūtakerua o te 7^{2}.
