Question

If a is a nonnegative real number and n is a positive integer, then . a.true b.false

Answer 1

I added a screenshot of the complete question.

Answer:
True

Explanation:
Rules of the root are as follows:
$\sqrt[n]{x} = x^{ \frac{1}{n}} \\ \sqrt[n]{x} * \sqrt[n]{y} = \sqrt[n]{xy} \\ \sqrt[n]{ \frac{x}{y}} = \frac{ \sqrt[n]{x} }{ \sqrt[n]{y} }$

Now the given is:
$\sqrt[n]{a} = a^{ \frac{1}{n}}$
This rule is the same as the first rule mentioned above, therefore, it is correct.
We use this rule to convert roots into powers which facilitates solving the problems given
