Tohaina
Kua tāruatia ki te papatopenga
a^{2}>2
Me tāpiri te 2 ki ngā taha e rua.
a^{2}>\left(\sqrt{2}\right)^{2}
Tātaitia te pūtakerua o 2 kia tae ki \sqrt{2}. Tuhia anō te 2 hei \left(\sqrt{2}\right)^{2}.
|a|>\sqrt{2}
E mau ana te koreōrite mō |a|>\sqrt{2}.
a<-\sqrt{2}\text{; }a>\sqrt{2}
Tuhia anō te |a|>\sqrt{2} hei a<-\sqrt{2}\text{; }a>\sqrt{2}.
