The square root of ? 125 is ? 3. So ? 125 is ? 6 times ? 3. And 6 times ? 3 is ? 18. So the square root of 125 is ? 18.
Here we will define, analyze, simplify, and calculate the square root of 125. We start off with the definition and then answer some common questions about the square root of 125. Then, we will show you different ways of calculating the square root of 125 with and without a computer or calculator. We have a lot of information to share, so let's get started!
The square root of 125 is a rational number if 125 is a perfect square. It is an irrational number if it is not a perfect square. Since 125 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 125?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.

Every non-negative real number a has a unique non-negative square root, called the principal square root, which is denoted by √a, where √ is called the radical sign or radix. For example, the principal square root of 9 is 3, denoted √9 = 3, because 32 = 3 ^ 3 = 9 and 3 is non-negative. The term whose root is being considered is known as the radicand. The radicand is the number or expression underneath the radical sign, in this example 9.
About Number 1. The number 1 is not a prime number, but a divider for every natural number. It is often taken as the smallest natural number (however, some authors include the natural numbers from zero). Your prime factorization is the empty product with 0 factors, which is defined as having a value of 1. The one is often referred to as one of the five most important constants of analysis (besides 0, p, e, and i). Number one is also used in other meanings in mathematics, such as a neutral element for multiplication in a ring, called the identity element. In these systems, other rules can apply, so does 1 + 1 different meanings and can give different results. With 1 are in linear algebra and vectors and one Einsmatrizen whose elements are all equal to the identity element, and refers to the identity map. (Source: www.mathspage.com)
