always
sometimes
never

Answer 1

thank you

Answer 2

if we have\[\sqrt{25}\]
written as

\[25^{1/2}\]

I do not believe this is in the denominator?

Answer 3

Actually it is true.

They are saying\[\sqrt[3]{x}\to x^{1/3}\]notice that the 3 in the root went into the denominator of the exponent.
That is the denominator they are referring to.
The rule in general is\[\sqrt[b]{x^a}=x^{a/b}\]her the root was called b and as you can see, it too went into the denominator.
