Question

I don’t know how to do these I’m so confused. Explain as well cause I will more than likely be tested on these.

Answer 1

Explanation:

`\sqrt[3]{27} = 3`

Because 3×3×3=27, or 3³=27

`\sqrt[4]{81} = 3`

Because 3×3×3×3=81, or 3⁴=81

`\sqrt[3]{ - 64} = - 4`

Because:

`\sqrt[ 3]{ - 64} = - \sqrt[3]{ {4}^(3) } = - 4`

`\sqrt[3]{1} = 1`

Because: 1×1×1=1, or 1³=1

Hope this helps!
