Answer :

To express \(\sqrt{200}\) in its simplest radical form, we need to simplify the expression under the square root. Here are the steps to follow:

1. Factor the number 200: We search for factors of 200 that are perfect squares. The factors are:
[tex]\[ 200 = 2 \times 100 \][/tex]
We notice that 100 is a perfect square (since \(10^2 = 100\)).

2. Separate the square root of the product:
We can write the expression as:
[tex]\[ \sqrt{200} = \sqrt{2 \times 100} \][/tex]

3. Apply the property of square roots: The square root of a product is the product of the square roots. Thus,
[tex]\[ \sqrt{200} = \sqrt{2} \times \sqrt{100} \][/tex]

4. Simplify the perfect square: Since \(\sqrt{100} = 10\),
[tex]\[ \sqrt{200} = \sqrt{2} \times 10 \][/tex]

5. Combine the terms: This gives us:
[tex]\[ \sqrt{200} = 10\sqrt{2} \][/tex]

Thus, the simplest radical form of \(\sqrt{200}\) is:
[tex]\[ \boxed{10\sqrt{2}} \][/tex]

Additionally, the numerical approximation of \(\sqrt{200}\) is approximately:
[tex]\[ 10\sqrt{2} \approx 14.142135623730951 \][/tex]
