The difference between the square root and the arithmetic square root is 1 Different definitions.
Square root: Generally speaking, if the square of a number X is equal to A, then this number X is called the square root of A..
Arithmetic square root: Generally speaking, if the square of a positive number X is equal to A, that is, then this positive number X is called the arithmetic square root of A (specifically, the arithmetic square root of 0 is 0).
2. The numbers are different
Square root: A positive number has two square roots in opposite directions.
Arithmetic square root: There is only one arithmetic square root of a positive number, and this number is a positive number.
3. Different expressions
The square root is expressed as (√ a)
The arithmetic square root is recorded as √ a.
The basic concept of square root is also called quadratic square root, which means that the result of a real number is equal to the result of a non-negative real number, expressed as [√ ~].
The square root of a nonnegative real number is called the arithmetic square root. Positive numbers have two square roots; 0 has only one square root, which is 0 itself; Negative numbers have no square root. For example, the square root of 9 is 3 Note: Sometimes the square root we say refers to the arithmetic square root. Simply put, it is a number. If it is 9, it is the square of 3; If it is 4, it is the square of 2.
