The square root of 169 is 13. To understand why this is the case, we can start by recalling the definition of a square root: it is a value that, when multiplied by itself, gives the original number. In this instance, if we calculate 13 multiplied by 13 (or 13^2), we find that it equals 169, confirming that 13 is indeed the square root of 169.

In competitive exams, it is important to be familiar with perfect squares, which are the squares of whole numbers. The number 169 is a perfect square, as it is derived from squaring the integer 13. Recognizing perfect squares can save time and improve accuracy during exams. For instance, knowing that 12^2 is 144 and 14^2 is 196 allows you to quickly identify that 169 must be between these two squares, leading you directly to the conclusion that its square root is 13.

Additionally, understanding the properties of square roots can enhance your problem-solving skills. Square roots are often encountered in various mathematical contexts, including geometry and algebra. Being able to quickly determine square roots will not only help in direct questions but also in more complex problems where these roots are used as part of larger calculations. Therefore, mastering the concept of square roots, especially for numbers like 169, is essential for success in competitive examinations.
