Question

Help me on this please

Answer 1

`\sqrt[3]{64}`

Answer:4

Multiply by 4 ( 3 times) because of the number 3 from the square root .

Answer : A

Answer 2

For this case we must evaluate the following expression:

`\sqrt [3] {64}`

By definition, we know that:

`64 = 2 * 2 * 2 * 2 * 2 * 2 = 2 ^ 6`

Also, by definition of properties of powers and roots we have;

`\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}`

So, rewriting the expression we have:

`\sqrt [3] {2 ^ 6} = 2 ^ {\frac {6} {3}} = 2 ^ 2 = 4`

Option A
