For non-negative real numbers, the square root refers to the real number equal to the result of the multiplication, expressed as ±(√x), and is read as the square root of x or x under the positive and negative root numbers. The non-negative square root is called the arithmetic square root. The square root of a positive integer is usually an irrational number. It can be defined by the following formula: In the fractional index, we have: According to the definition, we can know that the square root operation satisfies the distribution law for multiplication, that is, note that if n is a non-negative real number, then it must be a positive number, but there are positive and negative solutions. . Should be equal to ±; that is (see absolute value).
