sqrt169

sqrt169 refers to the mathematical operation of finding the square root of the number 169. The square root of a number is a value that, when multiplied by itself, gives the original number. In this case, we are looking for a number that, when multiplied by itself, equals 169.

The principal square root of 169 is 13. This is because 13 multiplied by 13 (13 * 13) equals 169. The symbol for the square root is $\sqrt{}$. So, $\sqrt{169} = 13$.

It is also important to note that every positive number has two square roots: a positive one and a negative one. Therefore, -13 is also a square root of 169, as (-13) * (-13) = 169. However, when the radical symbol $\sqrt{}$ is used without any preceding sign, it typically denotes the principal (positive) square root.

The number 169 is a perfect square because its square root is an integer. This means that 169 can be expressed as the square of an integer. Perfect squares are common in mathematics and have various applications in fields like geometry and algebra.
