x\times 49\sqrt{7}=7
Tauwehea te 16807=49^{2}\times 7. Tuhia anō te pūtake rua o te hua \sqrt{49^{2}\times 7} hei hua o ngā pūtake rua \sqrt{49^{2}}\sqrt{7}. Tuhia te pūtakerua o te 49^{2}.
49\sqrt{7}x=7
He hanga arowhānui tō te whārite.
\frac{49\sqrt{7}x}{49\sqrt{7}}=\frac{7}{49\sqrt{7}}
Whakawehea ngā taha e rua ki te 49\sqrt{7}.
x=\frac{7}{49\sqrt{7}}
Mā te whakawehe ki te 49\sqrt{7} ka wetekia te whakareanga ki te 49\sqrt{7}.
x=\frac{\sqrt{7}}{49}
Whakawehe 7 ki te 49\sqrt{7}.
