Please help thank you

Answer 1

For this case we have the following expression:

`\sqrt {64}`

We have to:

`64 = 8 * 8 = 8 ^ 2`

By definition of properties of powers and roots we have to meet:

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

Then, rewriting the expression we have:

`\sqrt {8 ^ 2} = 8 ^ {\frac {2} {2}} = 8 ^ 1 = 8`

Thus, we have that the result is a whole number "8".

Answer:

whole number
