<s>[INST] What is the square root, and how do I calculate it? [/INST] The square root of a number is a value that, when multiplied by itself, gives that number. In mathematical notation, the square root of a number "x" is denoted as √x or x^(1/2).

To calculate the square root of a number, you can use a calculator or perform the computation by hand using a variety of methods, such as the long division method, the Babylonian method, or the Newton-Raphson method. For most numbers, an approximation to the square root can be found using a calculator or by using estimation techniques.</s>\ <s>[INST] How would you find the square root of a negative number then? [/INST] You can't find the square root of a negative number because negative numbers can't be square. In order for a number to have a square root, it must first be considered square. We then reverse this process to find the root. Since negatives cancel out, the product of a number with itself will always be positive, so the set of all numbers that you could find the square root of has no negative numbers.</s>
