4\sqrt{3}x=-4\sqrt{5}
Tauwehea te 80=4^{2}\times 5. Tuhia anō te pūtake rua o te hua \sqrt{4^{2}\times 5} hei hua o ngā pūtake rua \sqrt{4^{2}}\sqrt{5}. Tuhia te pūtakerua o te 4^{2}.
\frac{4\sqrt{3}x}{4\sqrt{3}}=-\frac{4\sqrt{5}}{4\sqrt{3}}
Whakawehea ngā taha e rua ki te 4\sqrt{3}.
x=-\frac{4\sqrt{5}}{4\sqrt{3}}
Mā te whakawehe ki te 4\sqrt{3} ka wetekia te whakareanga ki te 4\sqrt{3}.
x=-\frac{\sqrt{15}}{3}
Whakawehe -4\sqrt{5} ki te 4\sqrt{3}.
