Finding the Square Root of 169

To find the square root of 169, we need to determine the number that, when multiplied by itself, gives us 169. Here's how we can do it:

1. Prime factorize 169
We can start by breaking down 169 into its prime factors:
169 = 13 x 13

2. Identify the perfect square factor
Since 13 is a prime number, we can't simplify it any further. However, we notice that 169 is the product of two identical factors of 13. This means that 169 is a perfect square, and its square root is simply the value of one of those factors.

3. Take the square root
Therefore, the square root of 169 is:
√169 = 13

So, the correct answer is option 'A': 13.

Note: options b, c, and d are incorrect as they all provide values that are not equal to the correct answer.
