The square root of 149 is not a perfect square, meaning it cannot be expressed as a whole number multiplied by itself. This makes it an irrational number, with an infinite decimal expansion. However, its approximation, approximately 12.20655562, plays a crucial role in various mathematical and practical applications.

Understanding Square Roots

Before delving into the specifics of the square root of 149, let’s first grasp the fundamental concept of square roots. In simple terms, a square root is a number that, when multiplied by itself, results in a given number. For example, the square root of 9 is 3 because 3 multiplied by itself equals 9.

Methods to Calculate the Square Root of 149

Due to the irrational nature of the square root of 149, obtaining its exact value is impossible. However, we can use various methods to approximate it with increasing accuracy.

1. Estimation and Guessing

We can start by considering the perfect squares that surround 149. The square of 12 is 144, and the square of 13 is 169. As 149 falls between these two squares, we know that its square root lies between 12 and 13. We can further refine our estimation by considering the relative positions of 149 within this range.
