The answer is 4 times the 4th root of 5. You would take out a 16, and the fourth root of that is 2 so 2 x 2 = 4 which would be outside the fourth root of 5.

Hope this helps! :)

Answer:

The correct option is A) 4 times the 4th root of 5 or
4\sqrt[4]{5}.

Explanation:

Consider the provided information.

Simplify 2 times the 4th root of 80

This can be written as:


2\sqrt[4]{80}


2\sqrt[4]{80}

The above expression can be written as:


2\sqrt[4]{2 * 2 * 2 * 2 * 5}


2 * 2\sqrt[4]{5}


4\sqrt[4]{5}

Thus, the correct option is A) 4 times the 4th root of 5 or
4\sqrt[4]{5}.
