Or equal to 0' because the square root of negative 3 is not possible. If you enter SQRT(-3) into a spreadsheet on your computer, you will get an error message saying something like 'argument must be greater It is just the most widely used answer.So you want to calculate the square root of negative 3? In mathematical terms, you want the solution to the following:

The answer to the question, the square root of a square number is NOT ALWAYS positive. By the same reasoning that the same number must be multiplied together to produce the larger number, -4 times -4 likewise equals 16. As an illustration, the square root of 16 is 4, so 4 times 4 equals 16.īut there are other square roots for the number 16. The square root of any number is essentially that number multiplied by itself, up to the largest possible number. Therefore, by definition, the square root of 4 cannot be +2, -2! Therefore, we only consider the square root function to be positive as a rule.īecause the square of both +2 and -2 is 4, but the square root of 4 can only take the value of +2, this leads to a lot of confusion, but that is the set of rules that we follow. This distinction is made because in a mathematical function f(x, y), there must be a separate value of y for each value of x. The mathematical function known as the square root really goes by the term positive square root function and produces all positive values, as would be expected.
