Question

Simplify 2 times the 4th root of 80

Answer 1

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 2

Answer:

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

Step-by-step 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:

$2\sqrt[4]{2 \times 2 \times 2 \times 2 \times 5}$

$2 \times 2\sqrt[4]{5}$

$4\sqrt[4]{5}$

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