Unfortunately, there are sometimes situations when you can rely only on yourself, what then? To prepare for this, you should remember several basic perfect square roots:

Maybe we aren't being very modest, but we think that the best answer to the question how to find the square root is straightforward: use the square root calculator! You can use it both on your computer and your smartphone to quickly estimate the square root of a given number. This alternative square root formula states that the square root of a number is a number raised to the exponent of the fraction one half:

There is also another common notation of square roots that could be more convenient in many complex calculations. It is because √0 = 0 and zero is neither positive nor negative. The only number that has one square root is zero. However, for many practical purposes, we usually use the positive one. Each positive real number always has two square roots - the first is positive and second is negative. Where ⟺ is a mathematical symbol that means if and only if. Therefore, the square root formula can be expressed as: The square root of a given number x is every number y whose square y² = y*y yields the original number x. In this article, we will focus on the square root definition only. Nonetheless, we sometimes add to this list some more advanced operations and manipulations: square roots, exponentiation, logarithmic functions and even trigonometric functions (e.g., sine and cosine). In mathematics, the traditional operations on numbers are addition, subtraction, multiplication, and division. Thus, the word radical doesn't mean far-reaching or extreme, but instead foundational, reaching the root cause. x is called a root or radical because it is the hidden base of a. The last question is why is the square root operation called root regardless of its true origin? The explanation should become more evident if we write the equation x = ⁿ√a in a different form: xⁿ = a. The notation of the higher degrees of a root has been suggested by Albert Girard who placed the degree index within the opening of the radical sign, e.g., ³√ or ⁴√. Although the radical symbol with vinculum is now in everyday use, we usually omit this overline in the many texts, like in articles on the internet. The "bar" is known as a vinculum in Latin, meaning bond. The first use of the square root symbol √ didn't include the horizontal "bar" over the numbers inside the square root (or radical) symbol, √‾. another theory states that square root symbol was taken from the Arabic letter ج that was placed in its original form of ﺟ in the word جذر - root (the Arabic language is written from right to left).many scholars believe that square roots originate from the letter "r" - the first letter of the Latin word radix meaning root,.However, the origin of the root symbol √ is still largely speculative. Many other documents show that square roots were also used by the ancient Egyptians, Indians, Greeks, and Chinese. The earliest clay tablet with the correct value of up to 5 decimal places of √2 = 1.41421 comes from Babylonia (1800 BC - 1600 BC). The operation of the square root of a number was already known in antiquity. In that way, we introduce complex numbers which find broad applications in physics and mathematics. Finally, if you are persistent enough, you will find out that square root of a negative number is, in fact, possible. There, we explain what is the derivative of a square root using a fundamental square root definition we also elaborate on how to calculate square roots of exponents or square roots of fractions.
