Answer:

Explanation:

Given :
$\sqrt[4]{81x^(20)y^(8)}$

To Find: What is a simpler form of the radical expression?

Solution:

$\sqrt[4]{81x^(20)y^(8)}$ --A

81 can be written as
3^4

x^(20)=(x^5)^4

y^(8)=(y^2)^4

Substitute the values in A

$\sqrt[4]{3^4 (x^5)^4 (y^2)^4}$

3x^5y^2

Thus Option C is correct.

is a simpler form of the radical expression
