To express $\sqrt{200}$ in its simplest radical form, follow these steps:

1. Factor the number under the square root: $200 = 2^3 \times 5^2$

2. Group the perfect squares: $200 = (2^2 \times 5^2) \times 2$

3. Take the square root of the perfect squares: $\sqrt{200} = \sqrt{(2^2 \times 5^2) \times 2} = 2 \times 5 \times \sqrt{2} = 10\sqrt{2}$

Thus, the simplest radical form of $\sqrt{200}$ is: $\boxed{10\sqrt{2}}$
