Tohaina
Kua tāruatia ki te papatopenga
x^{2}<\left(\sqrt{5}\right)^{2}
Tātaitia te pūtakerua o 5 kia tae ki \sqrt{5}. Tuhia anō te 5 hei \left(\sqrt{5}\right)^{2}.
|x|<\sqrt{5}
E mau ana te koreōrite mō |x|<\sqrt{5}.
x\in \left(-\sqrt{5},\sqrt{5}\right)
Tuhia anō te |x|<\sqrt{5} hei x\in \left(-\sqrt{5},\sqrt{5}\right).
