Answer 1

-12

Explanation:

Apply the radical rule :
`\sqrt[n]{-a} =-\sqrt[n]{a}`

Therefore,
`\sqrt[3]{-1728} =-\sqrt[3]{1728}`

Factorise 1728:
`1728=12^3`

Therefore,
`\sqrt[3]{-1728} =-\sqrt[3]{12^3}`

Apply the radical rule:
`\sqrt[n]{a^n} =a, \ \ \ \ a\geq 0`

Therefore,
`-\sqrt[3]{12^3}=-12`
