Answer 1

9.
`\sqrt[n]{x}`

`\sqrt[6]{-64}`

`\sqrt[6]{64 * (-1)}`

`\sqrt[6]{64}\sqrt[6]{-1}`

`2i`

10.
`\sqrt[n]{x}`

`\sqrt[3]{128}`

`\sqrt[3]{64 * 2}`

`\sqrt[3]{64}\sqrt[3]{2}`

`4\sqrt[3]{2}`

11.
`\sqrt[n]{x}`

`\sqrt[10}{1024}`

`2`

12.
`\sqrt[n]{x}`

`\sqrt[7]{(8√(2))/(2187)}`

`\frac{\sqrt[7]{8√(2)}}{\sqrt[7]{2187}}`

`\frac{\sqrt[7]{8√(2)}}{\sqrt[7]{(3)^(7)}}`

`\frac{\sqrt[7]{8√(2)}}{3}`
