Kua tāruatia ki te papatopenga
x^{2}>\left(2\sqrt{2}\right)^{2}
Tātaitia te pūtakerua o 8 kia tae ki 2\sqrt{2}. Tuhia anō te 8 hei \left(2\sqrt{2}\right)^{2}.
|x|>2\sqrt{2}
E mau ana te koreōrite mō |x|>2\sqrt{2}.
x<-2\sqrt{2}\text{; }x>2\sqrt{2}
Tuhia anō te |x|>2\sqrt{2} hei x<-2\sqrt{2}\text{; }x>2\sqrt{2}.
