To simplify the square root of 196, you can factorize the number under the square root sign and look for perfect square factors. In this case, 196 is a perfect square since it can be expressed as the square of a whole number.

The prime factorization of 196 is:

196 = 2 * 2 * 7 * 7

Now, group the factors into pairs, where each pair consists of two identical factors:

196 = (2 * 2) * (7 * 7)

Simplifying further:

196 = 4 * 49

Since both 4 and 49 are perfect squares, we can simplify:

196 = (2^2) * (7^2)

Taking the square root:

√196 = √(2^2 * 7^2)

Using the property of square roots, we can split the square root:

√196 = √(2^2) * √(7^2)

Simplifying:

√196 = 2 * 7

√196 = 14

Therefore, the simplified square root of 196 is 14.
