Question

How do you write `root3(8^3)` as a fractional exponent?

Answer 1

`8`

Explanation:

By example: Suppose we had `x^(a/b)` this is the same as `root(b)(x^a)`

So using this example and reversing the process we find that:

`root(3)(8^3)" is the same as "8^(3/3)`

This is the same as `8^1 = 8`

So `root(3)(8^3) = 8`
