2 câu trả lời

${ 4\sqrt[]{24} - 2\sqrt[]{54} + 3\sqrt[]{6} - \sqrt[]{150} }$

${ = 4\sqrt[]{4.6} - 2\sqrt[]{9.6} + 3\sqrt[]{6} - \sqrt[]{25.6} }$

${ = 8\sqrt[]{6} - 6\sqrt[]{6} + 3\sqrt[]{6} - 5\sqrt[]{6}}$

${ = 0 }$

`4\sqrt{24} - 2\sqrt{54} + 3\sqrt{6} - \sqrt{150}`

`= 2\sqrt{6} + 3\sqrt{6} - \sqrt{150}`

`= 5\sqrt{6} - \sqrt{150}`

`= 5\sqrt{6} - 5\sqrt{6}`

`= 0`
