Answer: The simplified form of the radical is
20x^(50).

Step-by-step explanation: We are given to find the simplified form of the following radical:


R=\sqrt{400x^(100)}.

We will be using the following square root property:


√(a)=a^{(1)/(2)}.

The simplification is as follows:


R\\\\=\sqrt{400x^(100)}\\\\=(400x^(100))^(1)/(2)\\\\=(20^2x^(100))^(1)/(2)\\\\=20^{2*(1)/(2)}* x^{100*(1)/(2)}\\\\=20* x^(50)\\\\=20x^(50).

Thus, the simplified form of the radical is
20x^(50).

\sqrt{400x^(100)}=\sqrt{(20x^(50))^(2)}\\\\=20x^(50)

We suppose you intend this to match the 4th selection.
